Only play esea if vac banned or faceit banned
play faceit premium, free faceit is even worse than mm
ESEA has a better anti cheat but less players.
I personally like it. Although the waiting time is a bit high, the experience is much more enjoyable than the one FaceIt premium (I had both), for the following reasons: players are less toxic (My FaceIt premium experience is horrendous, every match or so I would meet at least one toxic person, that would tilt easily and throw the game; whereas on ESEA, I barely met such people), the ranking system is better *Imo* (you don't get punished as harshly if you lose). Also, idk if it is just me, but in my experience, FaceIt premium is also filled with Russians and Turks which don't really speak English, in contrast, those 2 nationalities on ESEA can actually speak English and are actually willing to cooperate with you + the player base of ESEA is consisted of old players, which have been playing the game for some time
Essentially, I would recommend ESEA if you are solo queueing and FaceIt if you have friends to queue up with
