The real question is whether you'd actually *use* premium features or just pay to make the ads go away. Those are two different things, and a lot of people confuse them. If you're mainly annoyed by ads and just want to play casually, premium probably isn't worth it - you'd be paying mostly for convenience. But if you're genuinely interested in improving through lessons and want better analysis tools to review your games, then yeah, it makes sense.
Here's the thing though: unlimited puzzle rush sounds cool until you realize most people don't grind puzzles that much anyway. The real value is in the analysis features and the video lessons library. Before you commit, go check out what those lessons actually cover and whether they match where you're weak in your game. If your friends are actually *doing* the lessons and improving, ask them which ones helped most. If they just upgraded and haven't touched them? That's your answer right there.
Also worth considering: other sites like Lichess are completely free and have solid analysis tools. The Chess.com premium advantage isn't huge if you're comfortable with a different interface. So maybe try running a few of your games through Lichess analysis first - if you're happy with that level of detail, save your money. If you find yourself wanting more, then premium starts to feel worth it.
