I own an OP-1 and a mess of other synths. The Deluge comes close. I love my OP-1 for its size and portability. Being able to hack up a song on an airplane exclusively on one device rules.
The Deluge is excellent and I like that they really try to prevent people from having to menu dive. But sometimes when I can't remember what the 3 key combo is, I really wish it has a usable screen so I can look at a menu.
