I can't tell which is worse, but i can tell which is definitely bad.
First is CSGO. Not talking just about the most infamous nationality, there's assholes everywhere.
Playerbase is so soft. Maybe that's game mechanics restrictions, maybe something else, but playing on the same maps for over 10 years (yeah, 1.6 ect) is odd. Game has good maps to offer, but nah, i'll just play dust2. New maps are unbalanced and there's too much distracting elements.
Also, too much show-offs in community hub. Every time i open screenshot/artwork section, i see people showing their skins or simply posting anime and half naked girls. Like wtf?
Second is gonna be GTAO. I can't understand all that toxic level, why people are so angry there? They're abusing every single feature or glitch just to get kills. And after that they're letting themselves to spam sh1t into the chat.
Besides of that, i also can't understand some people who's farming there 24/7. Alone. Is this really that interesting to spend whole day repeating same actions just to buy a car you will never use again? Well, maybe in this case, Rockstar is the one to blame.
Also (PC) community hub is the same as CSGO. You'll find a single guy with 500+ friends who gets likes on his pictures and they're getting to the top. It would be ok, but his pictures are f*cking same. Hes just screenshoting his character's face and thats all. You can also find anime and half naked women there. On top of that, there's also panorama views spam. Cmon guys, i've seen this mountain 100 times from different angles, do something new. And just 5% are something that is really worth attention.
Third could be MGSV hub. Horny kiddos who abuse game mechanics and using hacks (PC, again). Not once i was basically f*cked in multiplayer fights. 1vs1 or 5vs5. Yeah, im not a noob nor e-sports pro, but i know how to aim. But skills won't always help you when there's a full server of invisible people using one-shot guns. Diversity? No, i just wanna use broken loadouts to bring myself to victory. And use auto aim.
Yeah, you can blame game mechanics for this, but that doesn't explain mods and cheats usage and playerbase lazyness.
