My Lichess rating is higher too, but you are all wrong. The standard is the same.
The lag on chess.com is ridiculous. I am fighting the whole time simply to secure the time allocated to me. IE 3mins does not mean 3 mins on chess.com.
If it feels lighter on lichess, it's because it is, not because other players are worse.
Neither use Elo. Chesscom uses Glicko and lichess.org uses Glicko-2
