I have a C90 and a V30 in a vertical recto 2x12 right now. The V30 dominates, it was hard to tell it even changed when I swapped in the C90. I don't know if they "fight", but the C90 is definitely a different beast in a closed cab. The lows are significantly limited by the cab volume I think.
I have a couple of 3/4 2x12 cabs, one with V30 and one with C90. They both have way more low-end than the recto 2x12, and even than my horizontal recto 2x12 with two G12K85. The recto cabs have a mid punch, but not much low end. The 3/4 with V30 has a lot more low end than you would expect from a V30 and the 3/4 with C90 shakes the house. But they both lack the tight, clear punch or the recto cabs.
I have a couple widebody closed-back ported 1x12 cabs, one with V30 and one with C90, and those sit somewhere in between the 3/4 2x12 and the recto 2x12. More low end than the recto cabs, but more high sizzle than the 3/4 2x12.
They're all great, honestly.
Interestingly, in a given cab I can use the GEQ in my Mark V and get the ones with V30 to sound pretty similar to the ones with C90 by adjusting 80 and 6600 sliders (this is just comparing same cab to same cab with different speakers). I could not get the open back to sound like the closed back because the dynamics are completely different. I can get the frequency balance similar, but the open and closed cabs sound completely different.
In the end I like the recto cabs for their punch, but the V30s in there are too piercing. And the open-back and ported cabs I like way better for cleans. They almost add a shimmer/reverb to the cleans. The closed cabs sound kind of dead on clean, where they add life to crunch.
