I spent a lot of time on chess.com (including paying for membership) but recently switched to lichess, because simply it feels a better, more polished, product. Love the fact it does not have ads (https://lichess.org/blog/YF-ZORQAACAA89PI/why-lichess-will-a.... ) unlike chess.com which is ad-infested.
Lichess is very customizable. Love the everyday tournaments and the community there as well. Would pay for it.
The in-game analysis in lichess is fantastic (too bad my favorite WebKit browser doesn't support WASM SIMD, looking at you Bug #222382 https://bugs.webkit.org/show_bug.cgi?id=222382 ) so I don't get the full Stockfish NNUE. That is the only thing I miss really.
Lichess has a monthly subscription you can get for $5 or a custom amount. Does nothing except except make your badge a different color. Totally worth it to support such a great site.
I have been teaching my daughter too. She is younger (she just turned 5), and En passant is one of the rules I voluntarily skipped (together with Castling). Pawns rules are already such a mess without it!
