I MUCH prefer mic'ing up Angled cabs. The speakers up top sound much less rumbly and more up-front, and most importantly, there is a lot less phase cancellation from standing waves bounding off the back of the parallel back. I don't know how people get usable tones out of micin'g the bottom speakers on an angled cab, personally. I could never for the life of me get it to work. They always sounded hollow as if I had two mics out of phase mic'ing it up.
Marshall straight cabs aren't too bad because they're slightly angled. But the top speakers still sound slighty better than the bottom ones, IMO.
It's the completely parallel straight cabs like Orange that I DREAD mic'ing up.
Honestly, it's also hard to compare apples to oranges on Marshall vs. Mesa cabs, even if they both have V30's. Both have radically different speakers, TBH. Even igorning that they both have their "propietary" take on the standard V30, the Marshall V30 is almost always 16 ohms while the Mesa is almost always 8. Even if you compare straigh up Mesa 16 vs. 8 ohms, there is a world of differnce. Also, the cab construction and materials are radically different.
I will say, though, out of the two most comparable analogs would be the Mesa Recto vs Traditional cab. And I think the Recto is actually the tighter of the two. The low-end is pushed down lower where it's more deep and controlled rather than stuffy and slightly muddy in the low mids. The high mid spike is also pushed higher up from the internal volume, thus making it more open and agressive rather than harsh. JMO, of course.
Honestly, the Recto cab has become so overused that it gets kinda boring to listen to it again and again. But they used it so much because it just pumps out the right frequencies for Metal, IMO.
