Marshall 1959 or 1987? - Pros and Cons

In this video I compare the two most widely used Marshall JMP amps. Super Lead vs 50W Lead, or model 1959 vs model 1987. Both are from the early 1970s. I'm using a 1971 1960A +1960B Full stack (G12M25 75Hz Pulsonic Greenbacks) and a 2008 Gibson Les Paul R9. I'm playing the Super Lead with both cabs and the 50W lead with the top cab. Only the cab is close miked. The close mic is a 548 and the room mic is a 414XL2. I'm using API 312 Mic preamps.
