I've got both MIT and MIJ OC2s as well, and did a pretty extensive octaver deep dive when I first got a HX Effects. I agree with @Smoove-Groove that they have pretty much the same sound. I wasn't aware about @JimmyM's point that they used the same board... I haven't checked mine, but maybe that's why they sound so similar.
EDIT: I've been interested to check out an OC5 for a long time to see if the vintage mode actually compares to the OC2 as much as they say it does.
I also agree with @Jakeman about the Octabvre. I have a MkII and the extra features are what make that one a better OC2 than the OC2.
That said, I use my C4 (OC2 sound) and Stomp's Bass Octaver (for a not-OC2 sound) on my main board. I already have both on there and pedalboard real estate is at a premium, and I can use an expression pedal with both to achieve the same sub-only control that the Octabvre has. Also because the Octabvre has become an increasingly rare (and expensive!) bird. All it would take is one drunken idiot spilling a beer on it.....
