Hi, just like you, I’ve been between the Prime Go and the Prime 2. I already purchased the Prime Go and have had it for a little under a month. Coming from big controllers like the Traktor Kontrol S4 and other decks/mixers/DJ coffins, etc. previous years, the Prime Go is a welcome change from always having to lug tons of things around like a laptop or always having to have a power supply nearby.
I was considering the Prime 2 solely for the following reasons: two FX banks (prime Go only lets you use one FX but can use it with both track 1 & track 2 simultaneously); you can see the individual volumes of each track + master (can only see the master volume on the Prime Go); and certain positions of things like headphone volume adjust, etc. Things like the horizontal EQs and the small platters don’t really bother me because you get used to the EQs fairly quickly and I only use the platters for beatmatching… which it works plenty fine for.
I ultimately decided for sticking with the Prime Go because it truly is basically the same as the Prime 2, just cheaper (you can get the Prime 4 used for the same price as Prime 2 on ebay), and way more portable. If you’re like me, a hobbiest who just wants to have a dependable and convenient setup to mix some tunes but with a unit that is powerful enough if I have to play anywhere/anytime (Prime Go has great ports for this), then you can’t go wrong with the Prime Go. Sure, it’s easy to miss little things like those I mentioned above, but is it really worth the extra money, extra weight (almost double), and extra size (only 3 inches smaller than the massive Prime 4)? To me, it is not but I understand why it might be for some people who will make more of a living with this equipment.
I can’t emphasize enough how powerful the Prime Go is. I mean, while it’s definitely small (but not abnormally small that it feels like a toy), this thing is $1,000 and comes with nearly all the software features as its bigger, heavier, more expensive, and “more professional” siblings. Understandably, it gets some flak because of its size but, to me, it’s just as good and definitely good enough for me.
Hope this helps.
