Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Immenseley configurable
As with any KDE app, Dolphin, allows adding or modifying toolbar buttons and keyboard shortcuts.
Pro Can split views
Dolphin supports splitting the view in two navigational areas, this way you can navigate two different directories at the same time.
Pro Integrated terminal
Pressing F4 with any opened folder on a mounted path opens a console within dolphin.
Pro Also has a refresh option
Dolphin is without a doubt the best fully functional and easy to use and multitask with.
Dolphin also has a refresh button which no other File manager has. It's great for tracking a large files transfer; that's what file managers are for - good common sense.
Pro Easy to extend with plugins
Dolphin follows KDE's philosophy of being extendable and configurable. It can easily be configured and customized through plugins.
Pro Auto mounts flash drives
Dolphin automatically identifies and mounts external flash drives.
Pro Fast at opening graphics folders
Pictures with or without previews is optional and selectable at the touch of a button.
Pro Does not use third party libraries
Unlike all those GTK-based file managers it does not have to rely on external written software for its functionality because KF5 is KDE SOftware and developed alongside.
Pro Keeps its state
It starts with last opened folders.

Pro Fully supports HiDPI
Supports HiDPI displays.
Pro Automatically centers items
In icons view mode, the space between files gets stretched so that there is never and annoying empty space at the right side of the window.
Pro Free/libre software
Released to the community under the Mozilla Public License (MPL), this software respect the FSF's four freedoms, including the freedom to use, modify, and redistribute with or without modification freely.
Pro Option to disable additional privacy concerns
Like fingerprint tracking.
Pro Takes care of privacy and security
Takes privacy seriously by blocking ads and trackers and not tracking people's searches. Things like HTTPS everywhere and no tracking are standard with Brave. In most other browsers, things like these are optional at best.
Pro Built-in adblocking
Other apps make it difficult to block ads without rooting your phone or going through unoptimized add-on stores, but Link Bubble blocks them out of the box, making browsing much less crowded. Contains an optional "Allow Brave Acceptable Ads" So you can support the site you truly enjoy.
Pro Optional feature for you to get reimbursed for viewing ads
Basic Attention Token; you can decide to opt into a new blockchain-based digital advertising system, giving publishers a better deal and users a share of the ad revenue for their attention.
Pro Now supports Chrome Webstore
It's now a faster, less intrusive Chrome.
Pro Tor is available right in the browser
Private Window with Tor hides your IP address from the sites you visit.
Pro Faster than Google Chrome
Brave consistently beats Chrome in speed, might have to do with less tracking being run in the background.
Pro Very fast
The fastest browser out there.
Pro Sync is now available
Option to synchronize data between devices using peer-to-peer connections. No sign-in required, only a sync code.
Pro Option to pay supported sites based on view time percentage
Set up automatic micro-donations. Brave will automatically divide a monthly donation among the top sites you visit.
And/or, you can decide which sites get what percentage of your donation. It’s called pinning.
Pro Supports the latest technologies
Brave regularly adds new functionalities like decentralized domain support and a native crypto wallet long before Chrome considers them. These features to be disabled in settings.
Pro Developed by creator of Mozilla and Javascript
Pro Cross-platform Web Browser
Brave is available on Windows, Linux, macOS, Android, iOS
Cons
Con May be a little slow on startup
Dolphin can be a little slow on startup (depending on distro, hardware etc...). Startup time can vary from a couple of seconds to up to a minute.
Con Can hang on remote file systems
It doesn't cope well with remote file system nicely like sshfs or any samba, like when network is not responding/very slow. It just hangs.
Con "Type" column too verbose
Despite having a large enough monitor, if you keep the size of the browser window small, the "Type" column (in "Details" view mode) insists on including the complete multipart MIME string, making the column so wide that trying to limit its width makes the column useless. Sorting by "Type" renders the list into an incomprehensible mess.
Con Poor optimization on later versions
Con Too simple
Feels weird on KDE because it has less customizing options Konqueror and any other KDE app have.
Con Can't perform ROOT actions
Developers set a constraint in Dolphin that deny Dolphin to run with root permissions. Hence, if you want to perform an action that require root permissions, such as rename a file in /etc/ folder, you are forced to use terminal or switch to another file manager.
Con Brave is an Ad company
Brave Software is a for-profit company (though users must opt into Brave ads and Brave doesn't track users.)
Con Download package is very large considering it as a browser
Brave takes on a lot of roles besides just browsing so it is understandably a larger file.
Con Useless built-in 'ad blocker'
Its adblocker is useless to be honest. Since the extension uBlock Origin is a great blocker by itself, the Brave ad blocker does not block every ad!
Con Quite intrusive advertisements, especially on Windows
Advertisements keep popping up in the Windows notification center. Must opt in to ad system, but no option to disable sound for ad notifications only.
Con Still dependent on Google
Since it's based on Chrome.
Con Uses much RAM
1 tab, 400+ RAM, also it depends on what website you're on.
Con Same security-holes as Chrome
On the desktop: Brave uses the same browser engine as Chrome, meaning it has the same security-holes as Chrome. Chrome is a big target for hackers (being the most popular browser in the world), and a webpage that will hack Chrome may also hack Brave.
However, Brave has security features that Chrome doesn't (such as a built-in adblocker). Those features will stop many hacking attempts.
Con Doesn't remove search engine ads
Con No reader view
Can be accessed with an extension though.
Con Dumbed down in the latest versions
In previous versions, Brave felt more like Firefox. Now it's been dumbed down, it feels more like Chrome/Chromium. For example: There's no menu-bar.
Con The iPhone version has some odd behavior
On reopening Brave, it often returns you to the "search results" page, rather than the webpage you had previously browsed to from the search results page. Might just be a specific configuration.
Con Cache dump
Doesn't clear cache well, shows same page even after emptying it until you ctrl+F5 to get fresh page every time you visit the page(s).
Con A browser for NFT-ers(?)
There would be less of a problem with using Web3 solutions if they weren't sometimes looking like an art for art's sake, a jerkcircle shoving down it's own topic down the users' throat. Replacing the Web 2.0 with another commercial solution is bound to end up as a reinvention of the wheel, where even more commercialization and direct monetization will push digital exclusion. Non-profit open source community has achieved great things while so far NFTs and cryptos are, not without a reason, ridiculed.
Con Sync issues
Unable to sync extensions, no cloud sync (only device sync).
Con Appearance
No options to customize apperance, and make the bookmarks appear on the home page, for instance.
Con Creator support limited
Most creators don't use it and so will not profit from the crypto system.
Con Poor Customer Support
Only customer support available in Brave community. Mods usually does not help.
Con Promotes search engines that track users such as Bing and Google
Google Search is the first search engine on the list.
Con Bookmark management
Bookmark management is not as seamless as other browsers.
Con No cloud sync like Firefox
Con Power hungry, uses much more battery power than other browsers
Per default Brave enables hardware acceleration which results in a much higher energy (battery) consumption than the most other web browsers.
Con Hypocritical/deceptive stance on privacy and advertisement
Brave is advertised as a browser that respects your privacy and blocks ads while still supporting content creators. However, at the same time the company is making deals with Facebook, Twitter and others to whitelist their trackers and ads
Con Bookmark button located on the left side of the URL bar and can't be moved
