3. Daily (correspondence) tournaments and a larger correspondence community. That's mostly what I play, since it allows me to play whenever and for as long as I want. 10-20 simultaneous games means there's always something for me to play. I can blitz out moves for all games in 15 minutes, or spend an hour thinking about one game.

I prefer lichess, but just can't have that experience so I pay for chess.com.

You can setup multiple pre-moves, but each one takes a minimum of 0.1 seconds. Lichess doesn't have this minimum time requirement, so it doesn't let you setup multiple pre-moves.

I much prefer Lichess' system for Bullet.
