Personally, i have been using the mobile version and I'm getting convenient with it as I'm not always free to visit the forum at home, so I usually visit and comment using my mobile devices.
If you also want to get a better user experience of the forum you can browse the forum using Tor browser it's also a privacy browser and a good one for the everyday user as it gives a better view of the website.
The thing with using desktop is the fact that Some features will be hiding on mobile while visible on the desktop versions. And the desktop versions are magnified as they should be due to screen size. One of the reason why I see people use phone is because of the keyboard typing, many people aren’t able to type properly on a system keyboard but since the mobile phones key board are more convenient since they are small and people use them frequently they are acquainted with it
Aside the fact that Tor browser actually helps in terms of privacy, I don’t see any other features that some other browsers do not have even the view in some browsers seems better
