what are the best tools on chess.com

If I missed something then sorry coz there are sooooooo many features that it's hard to remember all lop
Save the PGN files after every game, upload them for analysis. You can also upload them to Lichess.
It's like watching the replay of a sports game moment, or a movie scene. Watching things unfold step by step.

I see the appeal of the game analysis, however it can be slightly confusing to look at. Should you just focus on the blunders when running the analysis?

Without money all tools of chess.com are superficial and useless but the designs and trash articles make you feel it's helpful to improve chess.
How can only 8 puzzles/day with easy baby tactics like back rank mate, scholars mate, pawn promotion and other generated puzzles help you improve?
Chess.com also displays whole lot of ads and make money by using their poor community literally chess.com is for love of money not chess.
They never even took a look at https://www.chess.com/variants of the mobile site.
Premium account are giving too much profile to chess.com and the ads which chess.com's using to ill treat the free chess improvers are also making profit.
Sorry, for saying the truth but "Lichess is thousand times better than this!"
Chess.com does depend on $$ to survive and function. Note the ".com" part. What they offer premium members is fantastic. What they offer non-paying members is a small taste, a tiny appetizer to get you to sign up. Sure, if you don't like it, go to Lichess. No one is forcing you to stay with chess.com.
How should someone who is a beginner to intermediate use the tools on chess.com most effectively? What should you focus on the most, lessons, drills, tactics, or game analysis? There is so much that chess.com has to offer, but I want to make sure I am actually using it to get better and not just have fun doing puzzles or something. Thanks!
