When comparing MPV vs GOM-Player, the Slant community recommends MPV for most people. In the question“What are the best video players for Windows? (precision, hotkeys, timeline)” MPV is ranked 3rd while GOM-Player is ranked 6th. The most important reason people chose MPV is:

Pro Integrates with streaming services
When used with youtube-dl.
Pro Needs no additional codecs
Everything MPV needs to play media files is contained within which means no outside codecs are needed.
Pro Minimal interface
Click to open files and get Video with sound (and passthrough of codecs like DTS etc) for a perfect cinema experience. Works okay for many files.
Default window is not much more than a title bar - and if you drag/resize the window it resizes the video and leaves no empty areas. There is no visible control or display unless you use mouse/keyboard over the window.
This is the best player to use unless you're going for a media center (then use MPV based Plex Media Player to display and play the Plex Server library).
Pro Up to date
Always up to date, rapid development.
Pro Extremely responsive
Pro Caches livestreams
Intelligently caches livestreams and enables jumping within the cached stream.
Pro Auto add playlist
Automatically adds files with similar name to playlist
Pro Nice working skin engine
In contrast to some other popular players out there, the GOM Player skin engine really works out. Skins on GOM Player feel quite natural and everything is still very responsive. So even skins in use, the whole player doesn't feel bloated.
Pro Allows renaming of files while playing
Something I did not encounter often is the fact, that GOM Player has some magic trick up its sleeve. It mostly allows to rename the currently playing files and sometimes I can even move them. I cannot really tell how that works, but it does (playing from UNC network paths here (ntfs, windows)).
Pro Easy playback control
Whether it's switching audio channels, aspect ratio, playback size. All can be done easily via context menu or keyboard shortcuts or even mouse clicks if configured.
Con Minimal theme support
Con Lack of a typical GUI can be jarring to some
The minimal interface comes at the cost of beginner-friendliness. You need to know keyboard shortcuts by heart, settings are set in text files, right-clicking won't bring up a menu, etc.
Con Ads and a little bulk
Recent version got a bit bulkier than they were some years ago. If things get to much, use one of the older versions, they play mp4 and mkv just fine. Also needs some firewall tweaking to get rid of occasional ads in the free version.
