Lichess has some good lessons especially for beginners but they don't have audio like chess.com's. I think they are good though and what is neat about them is they are based on the studies feature, so anyone can create an interactive lesson on Lichess and share them. When my kids got interested in chess I created Lichess accounts for them. Some of chess.com's content helped me when I first started playing again, but I later found other free stuff that's just as good. It is nice to have it all in one place but I cancelled my membership when I found out I only got 25 puzzles a day with my "gold" membership. That is just lame.
