Using the UI- option does however provide a speedup for the VIC20 in that it avoids the drive having to wait 60us instead of 20us for every data bit sent (the extra 40us is required on the C64 because of the VIC-II stolen cycles). Hence use UI- if you want a "free" floppy speeder for your VIC20. Also, from what I've read "burst mode" was intended for the VIC20, but a fault in the 6522 design meant it was cancelled...
