This may sound like a bold statement BUT I own both & for me, that's all it is. Roland really screwed up with the naming of this synth! If they had to keep the Jupiter name, it should have been the "Jupiter S" (for supernatural). I do like the looks of it. It does need more controllers, a sequencer, vocoder & a bootable dedicated analog synth side(like the GT). I know it is not an analog synth(really should have been!!). Regardless, if you do not have a GT, it's a toss up to what to get. Maybe there will be some type of OS update down the road but who knows.....
