I was looking for some time for a good music editor. MuseScore was perfect except that it didn't let me use samples (unless I made a soundfont). LMMS is cool. Everything but the MIDI support (which was too quiet and lacked SF3 support) worked very well and was easy to figure out how to do. I also thought a few quality-of-life features could be added (I couldn't find a way to copy multiple tracks at once), but otherwise it was mostly feature-complete compared to other tools.
Here is my first attempt at making music with LMMS:
