When I bought my 1960AV, I tried everything Marshall made with my (at the time) JCM900 SL-X. I went with the Vintage-30 equipped AV because, to me, it had the best combination of sweetness and high-end rolloff without turning into mush at high volume (the Greenbacks sounded outrageous, but they really got kinda farty when you cranked a clean sound's output volume to "11").
To me, the '30s seem pretty versatile -- Hetfield got "the original" chunky sound out of them (though, as Ghost Flame indicated, he used Mesa), and yet a fluid, buttery lead is pretty easy to dial with 'em too.
Gearjunky brings up a great point: You shouldn't restrict yourself to just looking at Marshalls ... I bought one to match my head. Try everything you can with your own head and your own guitar (very important) and see what works for you -- you're the one who has to live with it.
