Here’s a Tim Shoebridge vid running through them
Polybrute over Rev 2 if you can find a deal on a used one, or if the new price isn’t too much.
The new Fantom is also a beast for pop/trap. Same with the Jupiter X and XM. I had the fantom, and will get an XM at some point.
I make trap/pop as well.
Out of all of these, though. Polybrute is what you can’t do with a VST. Rev2 is surpassed by Repro5, and the Roland stuff can also be done with Zenology Pro. Virus TI is amazing, too, and will always be a special synth to me.
I’ve owned every one of these, btw. Also owned Blofeld, hydra, quantum, prophet x, pro 3.
Out of your list, I would highly recommend the Rev2. Off list, Hydrasynth.
Also, start sequencing that Neutron with your Digitakt damnit!!! 
Just curious, but why?
Analog 4 was my first analog synth, and I’ve learned a lot from it. Sounds great, albeit sweet spots take a bit of seeking out (which actually was a great way to learn subtractive synthesis). It’s a unique machine, and I think a great way to learn it is by reverse engineering some patches you like.
To each their own indeed, but just interested in your perspective.

There was a discussion here around this a couple of weeks ago. I think it mainly boiled down to layout. For beginners or those new to synthesis you could argue that a more ‘traditional’ layout with more knobs per function and controls grouped around function assists when finding your way around. The A4 relies on at least a bit of synth experience otherwise it can be a frustrating experience.

There’s really no need to derail this thread with yet another A4 debate, plenty of that elsewhere on this forum! And the OP doesn’t seem interested in it anyhow.
