Only in terms of DOF, not in terms of shutter speed...
Besides, why buy a second camera body just to be able to use one of Canon's late-80s lenses, instead of a modern fast-focusing, weather sealed L lens with your current camera - for the same price?
Doesn't make much sense to me except for people who want to switch to FF anyway.

Also in terms of shutter speed, as ISO is not fixed......
There are two ways of looking at it, full frame gets you a higher image resolution. But APS-C gets you a smaller body. And more reach with tele lenses. Also, APS-C will be a bit cheaper even with an expensive 24mm f1.4, because if you switch to FF you would need also new standard zooms and what not.
I do not think it is strange at all, to get a 24mm f1.4 L USM II for an APS-C body, as 35mm FF equivalent. But you do not need a test to know how it will perform.... Just read the FF test and disregard the border/edge resolution figures (and the vinetting/light fall off).
It will be a stunning lens on APS-C as 35mm equivalent, just like it is a stunning lens on FF.
On the weather seal, only important if your camera, and you, are also weather sealed. Fast focussing it is, yes, but so is the non-USM 35mm f2.
In short, you do not really need an APS-C test when you have an FF test available.
