One of their esoteric synth emulations is BucketONE, based on the Crumar BIT 01/99 digitally controlled analog synths from the mid 80s. It has a really clean sound that I like, a little less typical analog but still warmer than purely digital or fm.

Full Bucket just released Broken Mini, an emulation of a broken MiniMoog. I can't really tell you more, since I haven't tested it, I'm installing as we speak.
Unusually for FB, there are a bunch of MiniMoog emulations out there, usually they emulate gear that hasn't been emulated.

Ableton finally added a special VST3 icon, so you can visually distinguish them from the VST2 plugins that you're probably wanting to phase out from your files.
