Hmm.... At some point I want to install a better bias system so that I can chuck whatever in there and bias it up, I'll have to try EL34's then. However, so far I've preferred 6550's in online clips. Not that that counts for much.
They are different. Bigger, cleaner, and more 3-D. They aren't the classic Marshall sound though. They don't crunch as nicely. I had them in a Plexi RI and it was a beast of an amp. Great for Jimi and SRV tones in conjunction with a TS, a fuzz, and a Uni-Vibe. I once turned the whole wooden living room floor of my 1947 FL home into a soundboard with that thing. Set up outside it could be heard MILES away.
 
Instead of going to bed I stayed up and played with the 57 at low volume. So far I'm not impressed. Here are two tracks of the same riff. One is the best I've gotten the 57 to sound on that track, the other is the best I've gotten the PZM to sound. EQ settings are the same across both tracks, the master is a hair higher for the 57, the cab is placed differently in the room since this was supposed to be a quick test, there is no beam blocker on for the 57, and the mic is right up against the grill cloth and centered on the cone.

SM57:


PZM:


I have some other clips, but those will have to wait until after some sleep. At the moment, I'm wondering if the whole time I thought I disliked Marshalls it's actually been the SM57 most people use on 'em. Not sure, more testing needed. I could just be crap at mic'ing with a 57. More comments to come with the rest of the clips.
 
@VonBonfire preliminary results seem to indicate that the 57 doesn't need the beam blocker as much as the PZM like you predicted, but the jury is still out for me.

You really should back it up an inch or two from the cloth and offset it from speaker dome/dust cap. Get about 3/4's of the way to the edge of the cone and see what happens. This could wind up being an open back cab+Marshall deal cause a 57 sounds absolutely dope on a 4x12 closed back IME whether the amp is a Plexi, 800, or DSL.
