I found this quote: "go with 35mm film. You get a larger negative -- 35mm vs. 24mm"
Is it right?
I found specs for 135 format negatives as 36x24mm and APS as 30x17mm
I have a suspicion that quote is referring to the film width, not the exposed image size !
If that's right, the difference beween the two formats is only 6 mm for a horizontal subject.
APS is 83% of the 135 size in that dimension, not the overstated 68%
Not so much over-claim in the vertical 70% instead of 68%
I'd go with 35mm for all the other reasons
Cropping room, body quality, lens quality, range of film choice, controllability of the camera - yeah Python's "what did the Romans do for us?" comes to mind
Which is why I'm going to sell my two APS SLRs
