I personally use Komodo most of the time, but lots of people use stockfish. What are the differences between engines and what do they help you improve on better compared to other engines.

Tl;DR Where do Stockfish and Komodo excel in?

  • IMO (and maybe only my opinion), this question has potential. Maybe the community would like the question better if it was narrowed down to something about the strengths and weaknesses of Stockfish vs the strengths & weaknesses of Komodo. Maybe a 3rd engine would fit, but - as the link in Allure's answer shows - there are literally hundreds of engines, and that's too much to discuss in this forum.

  • Before Stockfish had NNUE, people used Leela Zero because its board evaluation was (supposedly) more human-like in positional play. I'm not sure about now.

People use Stockfish because:

  1. It's free.
  2. It's the strongest engine. See CCRL for rating list and the fact that Stockfish has been crushing every other engine in the Top Chess Engine Championship.

However: if you're at the level where you don't care about making the best move but rather the move that takes your opponent out of their comfort zone (i.e., you are in the upper echelons of chess skill), then engine strength matters less than the diversity of moves that the engine might suggest. In that case having a wide variety of engines is good, and Stockfish becomes one of many possible tools at your disposal.
