In 135, TMAX 100 hands down, though FP4+ is a close second place. It doesn’t have the resolution you’ll get with 100TMX, but it’s very pretty and forgiving.
For medium format, TMAX 400 is a better option as it allows stopping down by 2 stops to get a little more DOF, the same for 4x5. I like having the extra speed as then I can stop down and get more focus.
I really wish I could get delta 3200 in 4x5, or Kodak started doing p3200 in sheet form. Delta 3200 in 120 is pretty good. You get the MF look, but about the same amount of granularity as a traditional cubic grain 400 speed in 135 format. My MF work is mostly 6x9 so I get basically 135 aspect ratio, but with a negative that is over 4x the size. Stepping up to 4x5 from that isn’t actually that big of a step up.
