as a person with multiple seasons of competitive experience in ugc, cevo, esea but who is no longer playing at least for the foreseeable future, i see you have two options.
1) pick esea, keep the community thriving. maybe they fuck up again, maybe they don't. personally, i was never really offended by esea. maybe they improve the quality after seeing how easily the community wanted to switch, maybe they don't. as far as i can see, if you want a LAN, and you want to see tf2 try and become the big esport that many have wanted for awhile, i think you have to go with esea. it is true that many top players strive for the lan to prove what they have been working for, and it is a big point in the decision.
2) you pick Cevo, hopefully it doesn't split the community, and hopefully everyone has fun. i think the spotlight on the game and the attention paid to it will drop within a year after choosing cevo, but if you are just looking to play the game and maybe have a more tight nit community then this is a solid option
i'm probably totally wrong and my opinion is shit but this is how I see it
