Update: It looks like the votes are clearly in favor of Lilypond. While Sibelius and Finale appear to be the "canonical" solutions, and MuseScore has a nice showing (albeit using a "development" version).
I'd like to produce my own edition of Paganini's Caprice No. 6, with guitar fingerings and ossias. I've tried muscript, and while it generally looks good, it can't handle the complex beaming. I've tried homebrewing my own typesetting system, but that's just going to take forever. So what can I use to reproduce this piece with 64-th note dodecatuplets and sixteenth-note tremolos?

This is the output I've been able to get with muscript (code demonstrated here):
