Lichess is one of the best things in chess. It is free, respected, open, and remarkably useful. If your goal is to review a game quickly, inspect engine lines, run studies, solve puzzles, or keep your overall chess workflow in one generous platform, Lichess is already excellent.
That is why the wrong comparison angle is to attack Lichess head-on. The stronger and more credible message is that free engine analysis and coaching-oriented improvement are different layers. You can admire Lichess and still need something more interpretive when raw analysis stops being enough.
