I don't like puzzles as well on Lichess. Both sites have puzzles that seem to call for computer moves, but I see these more often on Lichess.
Lichess is a joke compare to Chess.com in terms of rating strength and improvement !

If you’re curious how your Lichess rating stacks up on Chess.com, I’ve put together a data‑driven conversion method complete with interactive charts:

I’d love to hear your feedback!
My take: chess.com has better games and ui. However lichess is much better for analyzing, puzzles etc because it's free. If chess.com was free I would 100% be using it 100% of the time. But lichess is free and not for profit which is why it is better in studying
Edit: oh also people on lichess are nicer especially on forums
Well I am a member on Lichess and I have never experienced and abusive false a accusations against my play, and never any on Schemingmind either ... but have had enough on Chess.com to convince me not to be a paid member, an example recently was when I skewered an opponents two knights by pushing a pawn on and after my opponent took it with there Knight I moved my queen to the sixth rank attacking both un-defended pieces! Oh your not fair and worse... reporting you for your play Etc. the other 2 sites I play on never ever had any of this attitude only from chess.com opponents, that 35% who accuse everyone who may do well against them!!?
