Lichess is a bit sluggish in navigation, but it's almost purely community driven and you can feel that! I do support them and I really like their transparent philosophy, they even show you WHERE do they spend EVERY received $! Yes, there are some flaws, but me with other guys are actually making the website just better every day. Chess.com sure has their own philosophy, better moderation, better news articles (sometimes written by professional journalists), but hey, it's almost like a comparison of good paid service with good opensource community driven thing. Like... Windows vs Linux. Both do have their downsides, but the core philosophies are different and you just follow them or not.
