For me diabolical felt real good to play, but it was really frustrating to get in any games. Starting up epic felt real janky at the time. Idm was really fun and brought back Warsow memories. Quake seems still be somewhat relevant.
Yeah the game felt solid. The biggest problem imo was that it had too many gamemodes which split up the playerbase. I really enjoyed wipeout and duels.
I've mainly played Xonotic recently which has been fun.
