I am sooo.. happy with MuseScore.
I struggled for years trying to get going on Finale, but never could. A little reading, a few tutorials, asking a couple of questions, and I was on my way with MuseScore.
I use it for band leadsheets (melody line, chords, lyrics).
If I ever have a question that the Handbook, "Mastering MuseScore" (Marc Sabatella), or Google can't answer, posing a question at the forum usually gets answered accurately and quickly.
I was so thankful for MuseScore I made a monetary donation to the project.
