What are the performance differences between the spray on compound and polish, and the cream?
I'm not sure what you mean, if you mean cut? This was posted at the OPT forum about a year ago:

There is some confusion (in the OPT world) over DAT/SMAT, because at one time we were told they are all SMAT, but that apparently isn't the case any more. Here is what was posted over there about DAT/SMAT (again, about a year ago):
The polishes (Polish II, Hyper Polish, Finish) use SMAT while the rest contain DAT.
----BUT----
Dr G states that the products are unique formulations that don't comply with traditional SMAT/DAT descriptions and combine characteristics of both.
FWIW when FG400 came out and I asked if it was SMAT or DAT, this is what Mike Phillips said:
"Is it SMAT or DAT? Menzerna isn't' saying. Anything you read or hear from anyone else is speculation and in my opinion in not relevant because in the big picture you're going to pour out a bead of product onto the paint to use with a rotary buffer or apply some to the face of the pad on a DA Polisher and get to work.
How it's made is certainly interesting and I'm always just as curious as the next guy about abrasive technology, a case can even be made that I'm more curious. But at the end of the day the only really important factor is the results you achieve and the performance of the product, not what's in the bottle."
If that wasn't what you were asking, if you were asking about the usage of creme vs. spray...they all work pretty much the same, the sprayable ones have a higher solvent content since they need to be more "watery" to spray...I think the jury is out on whether the sprayable feature is good or bad, the idea is to be able to easily get an even application of product on the face of the pad...in practice you usually wind up with some on the pad (which may or may not be even), some on the machine, some on your arm, some on the car, some on the side of the house, the dog, etc. Plus people complain about the sprayers breaking (I haven't had that issue...sometimes they get a little clogged if you haven't used them for a while), so some Hyper users just transfer to a traditional bottle.
IME all the OPT polishes have long work time and easy wipeoff (Rasky's comments about the newest Hyper Compound notwithstanding), although I haven't used the newest versions of the Hyper products, or GPS, and the Primer is a pro-only product. I think the original attraction for me was that OPT said that you don't need to do any special cleaning or prep wipe to follow any of their polishes with an OPT coating (this was before they came out with their own prep wipe). They said just dry wipe the polish and coat; I still usually did an IPA wipe just on GP's, but it gave me more confidence given they stated I didn't need to do that.
