Vintage Acoustic varies. A 360 stack has a specific sound - big, round, juicy, with lots of blues and dark greens. A 370 has a drier, more orange/brown sound and is a bit raspy for my tastes. A 320, at least through a 408 cabinet, is closer to a 360, but more hi-fi if you will. None are better or worse, just different. The Grexa Acoustic USA 360 can be a big sound like the original, but it can also get full spectrum, and I think it is the best of the lot, assuming you can find one. I don't care for the Ampeg sound that much. It is like a 370 only even more on the raspy orange/brown end of things. They don't have all the different colors in their sound. I have liked what little I have heard from vintage Peavey iron, but I can't say all that much because I haven't used much of it. I had a small Kustom combo that sounded absolutely awful. I'm also not a huge fan of the 126 Acoustic combo I leave in the rehearsal space. It sounds like bass, but it isn't what I want to sound like live. As far as the modern stuff, I have a Carvin MB12 combo and extension cabinet that has the definition of a modern, hi-fi sound. It's good with the upright especially, but it can also be dialed in to get a bit darker, rounder sound if that's what you want. It cannot come close to a 360, but then nothing does. The Carvin is a couple little boxes that are easy to move in a way that the 360 isn't, so there's that.
I played through a Sunn 200T (I think) at one point and liked it a whole lot. I don't remember exactly what it sounded like, but I remember liking what I heard.
