Musescore is free and clunky. You’ll need to use the paid version if you want to see other people’s compositions. A lot of folks who do midi rips (using software to sequence a recording and then rip to notation and arrange ) do so on Musescore, so it’s where you’ll find other people’s versions of a lot of anime, video game, and genre compositions . Noteflight is very reasonably priced (and you can do 5 scores for free) and comes with a big music library and is much easier to use (and is what I use). It also provides a route to publish your pieces and get paid for them (including of licensed music, because it’s owned by one of the biggest publishers). Flat.io is the best app based one. Dorico is the most powerful but is extremely expensive. Finale stopped production last year, but had stand alone versions that didn’t require subscriptions far longer than most, and was the industry standard until last year.
