I use KOReader daily on my Kobo and my Boox Go 10.3 (Gen II) Lumi. I use BookFusion to sync with my iPhone. They all work great. KOReader doesn't have the most intuitive menu structure, but the plugin environment is excellent and there are several UI plugins that make using the software easier.

It's also great for jailbroken Kindles.
