Both sites are good. I think lichess is better but chess.com have great lessons & practice. Altough lichess also have amazing studies.
Lichess or chess.com- which one is better

Lichess has (almost =) everything chess.com has but for free.
Lichess has better analysis (closer to chessbase quality), a better engine, and simply more higher rated players.
Chess.com is better for forums and clubs, additionally the paid lessons are okay too.
Lichess GUI i like more, but that is more a preference thing.
I would say Chesscom is better if you have diamond membership, but lichess is better if you want smth for free.

If you are willing to spend a few bucks, chess.com all the way. If you don’t want to spend money, Lichess is better.

Against forum rules to discuss other chess sites. Maybe you should read the rules before posting.
If y'all post anything about Lichess being better than Chess.com on here, Erik Allebest sends his brainwaves into your computer & blows you up. This is true.

My huge wrong with lichess.org, that you can only see your rating if you're playing, and you can't show your IM, FM, CM, WIM, WGM or GM title.
So chess.com is more better!
everything you just pointed out are also on lichess and almost all of them is better on lichess.

CHESS.COM FOREVER
