From what I understand (rather than personal experience!), both of those cabs are awesome. I've seen and heard orange cabs - very very good, and I gather that the ENGL cabs are about the same in terms of build quality and sound quality.
If you're set on getting V30s, then either of those would do very nicely. I'd personally go for a matching cab (ie the ENGL), and probably horizontal so you can sit your combo on top of it (no that wouldn't be a problem).
In fact, if it was me, I'd probably stick in some G12K-100s, but that's another story altogether :D
