Pros
Pro Free, open source, and cross-platform
VLC is licensed under the CC-SA v3.0+ and available on Windows, OSX, and Linux with source code available here.

Pro Simple to setup and use
VLC is an incredibly robust application but very simple on the surface. It makes playing music simple, yet still manages to give the user all the tools he/she wants in a music player.
Pro Very versatile and easy to use
Pro Doesn't require additional codecs
Everything VLC needs to play media files is contained within which means no outside codecs are needed. This makes it one of the most hassle-free music players as it can play virtually anything as soon as it's installed.
Pro Tons of advanced settings
Besides basic configurations, video player has an extensive amount of adjustable settings.
Pro Doesn't manage your music library for you
You organize your music into folders any way you want. Want to play an album? Drag and drop. No tags, no confusion, no fluff. Easy.
Pro Can be almost completely keyboard-driven
VLC includes keyboard shortcuts for most actions. The video player can be controlled with simple and customizable keyboard commands.
Pro Surprisingly Lightest on Resources
Yes. Lightest. Even better than the ones known to be light. Both when playing music, only a single song or when playing a video. Either in terms of Ram and Cpu. Compared with almost all, including the ones from Windows like mpc-hc .. or light ones from Linux like Alsa Player, Audacious, SmPlayer .
Pro Can play every format video available (as of 2017)
Pro Supports a GUI interface and an ncurses terminal interface
Pro Can easily stream music across your home network from any device on the network
Using sftp/ssh music (and videos) can be streamed from any server on the network to any device running VLC. VLC can also be used as a webcam for streaming and snapshots. Amazing all in one package
Pro Large amount of extensions
VLC has a large amount of extensions.
Cons

Con Not really meant to be a music player
VLC is made to be a video player. Therefore, it won't carry out actions such as managing your music library.
Con Lacks libraries and advanced music player features
VLC is a media player first and foremost. There is no library management (aside from playlists), limited usage of tags, and no rating system. VLC is best at playing a file directly from a folder, but falls behind when it comes to helping you manage or find good songs in your music library.
Con Absence of personalization
VLC Player has only one basic interface in white or black, and overall personalization opportunities are quite narrow. Unfortunately, you're pretty much stuck to the default look.
Con Contains some insignificant but irritating flaws
Despite all keyboard shortcuts, the width of the picture can't be controlled by trackpad. Besides that, the VLC start-up window doesn’t open at the same place or the same width at which it was previously closed.
Con Sneaky about trial limitation and prices
Trial version only cleans 500 MB, but it does not disclose that limit before one pushes the button to clean after a scan. While it's OK to provide only limited functionality in a trial version, the appsshould be upfront about what the limitation is.
Especially with an app that is supposed to clean your system, it's really messed up to run an activity only partially, and then ask for money. This is clearly done to play on the insecurities of the less-than-tech-savvy users, who might believe that their machine is now in a worse state than before they ran the app, and need to pay now to get a clean system.
Even when trying to close the nag screen by pressing the little X in the corner, the X turns into "Don't leave yet, get your personal discount", which opens the website and gives you even more discount than their "Deal of the day" which is shown after you download the trial. So people who just go to the website to buy pay $89 (or $69 when they get a deal of the day), but when they pay from the nag screen, they only pay $56. That is not a good way to do business, and even if it were a solid app, it's hard to support these practices.
Con Space Lens reports more storage that the SSD actually provides
For example, a 480GB SSD with 70BG free, and the sum of the folders Space Lens shows in root is about 550GB. That's definitely wrong.
Con Provides no info about things it deletes
The app does not provide any additional information about the files it wants to delete, so the average user cannot make an informed choice what to remove and what to keep. For example, it might prompt you to remove languages other users of your Mac are using. That's not a good idea.
Con Uses just a tiny window for showing details about what the app tries to delete
In full screen view, the part of the screen where the app shows a list of things it wants to remove is about 8% of the screen. So you can see 8 items at a time (out of a list that has about 80 entries), and the name of each of those items is truncated. 75% of a 24"-screen is entirely blank in that view.
Con "Flush DNS Cache" will not boost speed
It will simply flush the DNS cache, so that each request for a web page will require a call to a DNS server first.
Con Claims it will "Free Up RAM"
People who have a clue about memory management will understand that on a Unix system RAM is typically fully used, because that is the way to optimize speed. Any attempt to "Free Up RAM" will lead to other stuff being loaded into RAM immediately: the app might "free" 2 GB of RAM, but if you come back to Safari and look at several tabs, it will soon be back to only 200 MB of free RAM.
Con Expensive
A full license is $89, but there's no way of telling how long you would get free updates. Owners of the previous version will have to pay 50% of that to upgrade. The subscription service is $39 per year. If there's a new major version in the next 3 years, subscription will be cheaper. All that fits with MacPaws being intransparent and sneaky.
