Can you guess the amp?

One is a solid state 20 Marshall combo from the 80s. 10" speaker.

One is a JTM45 amp with NOS valves and a 2 x 12" Greenback speakers.

Which is which? First amp or second?

Well, I can tell a difference in tone between the two. But as I have no idea what a real JTM 45 is supposed to sound like I cannot guess.

Too much going on there to tell if you were switching amps, pickups, guitars or effects. It would help if you said what you were doing as you did it; "this is amp A on the bridge, this is amp B on bridge, etc"
