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 Blocks all ads
You don't get interrupted or annoyed while browsing.
Pro Less data consumption - therefore, less money for mobile traffic
Almost 50% of data consumption goes to downloading ads and trackers. And you have to pay for this. With Free Adblocker Browser, you don't have this problem. You get more at a lesser cost.
Pro Blocks trackers and keeps your online privacy protected
Because no trackers are downloaded to your device, advertisers and third parties can't track what you are doing online.
Pro Keeps you safe from malware, viruses, and other scams
The Browser warns you if the website can bring some damage to your device.
Pro Friendly interface
Pro Ensures fast browsing
Because no ads and trackers are downloaded, pages load very quickly.
Pro Doesn't ruin the page when it refreshes
It reloads the last loaded webpage when it tries to refresh and you don't have internet service.
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 Android only
Free adblocker browser broke iOS support.
Con Not really free
To use advanced options you have to pay.
