Strongly agree with you. Both the chess playing UI and exploring the rest of the site -- lichess is vastly superior.
Prominent example when you click "Play" you go to https://www.chess.com/play and get presented with a chess board. At this point, it actually lets you make an initial move. But you're not playing anyone! You then need to click, for example, "Play online".
The rest of the site is disorganised. For example there's stuff under "Learn" and "Resources" and I can never remember where to find things.
This is just mindblowing to me. It's not just that I disagree but I think the opposite is true, and by a very large margin too. I guess people just have different preferences when it comes to UI but especially for fast time controls, I don't get how people put up with chess.com, it's outright unusable for me.
