[Honey]

I have also played PUBGM and PUBG Lite the reason i left was hackers and just bots, I was also at ace either the whole server was full with cheaters or just with bots.
@Honey, For CSGO, When the game got Free-to-play, Literally non-prime matchmaking you can't ever play, I left official matchmaking a long time ago after being global elite. I switched to FACEIT which have a 128 tick experience and seriously less cheaters, Yeah sometimes you do get smurfs but pretty less cheaters!

Yeahh the bots issue is quite horrendous, I have usually found that there aren't as many bots in 4 man squad games instead of the single/dobule player games, this might be true for you too.

On the other hand, about CS:GO I believe Valve made their anti cheat in the way that non prime matchmaking obviously was very bad when It first started, I too faced many hackers when I tried non prime matchamking (blatant spin botters) however I think the anticheat did that as It placed me in the lowest rank of their new "Trust Factor" and as I played more and more It improved my rank more and more.

Now if I do non prime matchmaking (with Friends) I do see hackers but not that common or blatant.
