What difference are you expecting it to make? I can't understand the point of a 68060 option in UAE, myself.

I still don't see how it would help unless it emulated a cycle-exact 50MHz 68060, and I somehow doubt thats the case. I suppose it could help you avoid writing a demo that requires oxypatcher, provided that when you used unimplemented instructions it brings execution speed in UAE down as slow as they are on a real amiga without oxypatcher (does it?).

So, IF the UAE 060 emulation does the things above, I would concede that point, but that is absolutely the only reason I can think of for using it, and its not a particularly compelling argument (if you're a democoder, you can just avoid those instructions by reading up on which ones are missing from the 060 and not using them).

It just seems like a waste of effort to me. In fact, I can't see much point in emulating anything above 68020+FPU, since that combination has all instructions used by Amiga software, and setting "68040" or "68060" in CPU options doesn't magically make the emulation any faster (or shouldn't).
