Finale vs Sibelius?

Have you used either/both? Which do you prefer? Pros/cons?

I've only used Finale, so I can't say how it compares to Sibelius. I will mention MuseScore, though, which is free, available for Windows, Mac, and Linux, and does all the basic stuff fairly well:

Apparently Sibelius supports Recycle now, which is the thing really grabbing my interest.
