There was the "Model 26" Deluxe, then the TV Front 5A3 Deluxe, then the 5B3, 5C3, and 5D3, and then the 5E3.
6SJ7 tubes are also dual triodes, like 12A*7 types. Only thing is, they are 8 pin and may be more difficult to find good tonal varieties, whereas the 12A*7 there are many more manufacturers therefore you can "taste test" more of them, not to mention you can try lower gain 12A*7 varieties.
For this reason and others, I'd suggest going with a 5E3.
