Here’s my love/hate list. More love than hate and most of my issues go away when I move on from making sounds to using them.
I love using neighbor tracks especially combined with playing the filter rez. 
I love performance mode although it’s very much trial and error. I hope performance mode gets expanded on. I dunno, maybe within a knob macro have knobs able to scale in relation to another, using the envelope shapes with the same parameters from the LFO page. Same deal with performance so for instance, moving knob a would scale knob b exponentially negative and knob c linear, positive and so on.
I don’t think the interface is quite as smooth to operate as the rest of the elektron boxes, yes, even the octatrack! Sure you can do everything without a lot of menu diving or combos, but I reach for the wrong knobs more.
Maybe it’s just my crappy brain, but 5 knobs in a row gets slightly less immediate, in terms of reaching for the right one without thinking. Maybe if E+J (or A +F?) were assignable to anything or to control performance macros?
Might seem strange, but i’d dig more pages with bigger graphics. The Monomachine graphics seem ridiculous and almost childishly huge and that’s a good thing! Feels more like play. I’d be happy to tap the osc buttons more, especially because the noise page is so lonely!
I see the analog4 largely as the spiritual successor to the monopoly. I think the 4 was kind of misleading, for me at least, in that the 4 isn’t so much that you have 4 tracks to work with, but that there is a great, to me at least, sense of cohesion capable between the 4 tracks. I got more into it when I stopped treating the tracks as four independent elements. I think there’s a reason it only has two outs.
To me, it’s seems the easiest, most painfree elektron box for switching things up on the fly. Once you get into it, so much love! It’s kits from the old school mixed with (savable!) scenes from the octatrack.
Make a sound, use a few patterns, sample it, save some sounds, load some new stuff, make some new stuff, repeat. I find it’s the most pro-ADD box they make, as long as you have the attention span to make sounds. 
To that end, I’d like to see a more “musical” performance based implementation of things like selecting track sounds, and I think editing and p-locking those (looooooong) parameter lists is a bit too error prone.
Still, the majority of other synths, analog or digital(!) are way more cumbersome to change things up.
The more I build up my own sounds and kits the smoother and more enjoyable the experience gets. There are some good presets, I think, maybe? but I can’t remember what they are and it defeats being able to quickly switch sounds if I have to audition a ton, so I don’t!
For me at least, it was helpful to think of some of the individual sounds more as templates with modulation routings and envelope shapes.
