Ranked in these QuestionsQuestion Ranking
Pros
Pro Great with large libraries
This program uses a tagging system to help you find the music you're looking for, and can even help find duplicates. It will also automatically sync with a folder, meaning you don't have to manually initiate a scan.
Pro Cool AutoTagger
The smartest auto tagger out there. It has an intelligent regular expression system to tag the files based on the filename contents. If the name contains something like Band -Album - Track -Title www.download.mp3, the system lets you filter the metadata fields.
Pro Large assortment of layouts
You can pretty much emulate your favorite media player layout inside of gmusicbrowser as it has a large assortment of pre-made layouts as well as an insurmountable amount of options for custom layouts.
Pro Remembers playing/pause status even after restart
With most other options, you have to start the player, wait a few seconds, then click Play. Gmusicbrowser spares you the wait and plays music automatically upon startup (if you were playing music when you closed it previously).
Pro Intelligent auto playlists
Automatically generated playlists with the criteria you decide. Great for big collections.
Pro Offers some skinning options
Qmmp allows the user to drastically change its look via skins. It can use Winamp and Xmms skins, as well as a list of 12 skins made specifically for qmmp that can be found here.
Pro Small single-window interface
Unlike more popular players that draw a huge window taking up the entire screen, with tons of knobs and menus popping out in new windows, qmmp gives you a single tiny window (that looks pretty much the same as Winamp used to look) with the basic controls and the playlist. The rest is available through a menu.
Pro Lightweight and supports almost all formats
Pro Plugin based
You can extend it with plugins.
Pro Qt-App
No matter what OS or desktop you use Qmmp will integrate well
Pro Clean and simple interface
Pro Depends on libaries
It depends on libaries instead of big fat toolkits like gstreamer.
Pro integrated file browser
Pro Supports cue sheets
Cons
Con It won't install on Linux Mint 21
Con Held back by performance issues
Can be very slow, uses a lot of resources, and has a decent amount of lag when going between songs.
Con Doesn't support media keys
Con Unusual keyboard shortcuts
Space does not pause, for instance. This would have been useful, as hitting the space bar is easier than finding the play/pause button - most music players use the space bar in this fashion.
Con Some plugins are outdated
Several plugins works on older versions of libraries no longer available for recent distros.

Con Poor library management
Initial load may have issue skipping parts of ones library, re-scanning may not resolved the issue. It also may tax ones CPU quite a lot, during these load attempts.
Con No WMA support
For those with older libraries that may still have unconverted WMA files, this can be a non-starter.
Con Large assortment of features and layouts may be confusing
Some people may find all of gmusicbrowsers layout and options daunting to figure out.
Con Interface is not particularly intuitive
