As of today (on chess.com since Jul 8, 2007), I have played 15,472 and done 1 puzzle and 1 lesson. 1415 rating in Blitz, and I play either 3min or 5min max.
I have played 79 games on Lichess since joining in May 10, 2015. 1716 in Blitz.
I always land up on chess.com because there are enough people that I open a challenge, I get a player on the other end within seconds. Not so on Lichess - I have waited for 30+ minutes on most occasions.
