Juno-ish is just a sonic reference, Zoetrope is definitely good for much bigger/different sounds as well. But to me, it is an ultimate pads machine. In any case, just trial it, I bought it after trialing it for, like, 15 minutes or such (and I already had most RE synths)
As for that harpsichord thing, I even never looked at it in the shop, but man, that thing looks even uglier than it sounds. The only thing it would be good for is doing a cover of Golden Brown... and I don't do covers
