It's just good in almost every way. It's super well-made, has tons of features, and is free, even including compute tasks like having servers run analysis on your games. It's like one of the nicest things on the internet, I swear.
The study and game analysis features in lichess are waaay ahead anything in chess.com. The only thing chess.com does better is having more content, lessons, etc. But you're probably better off buying courses in chessable, reading books and getting a good coach anyway.
