I think I understand that your looking for folks who used these powders for their loads, and are simply looking for what works best for them....
That said, and has been mentioned above, the 45 ACP is such a versatile round that the data for it is widely abundant. There are so many powders what WILL work with it's specific pressure range, that simply picking a powder is sometimes difficult.
I myself picked up an 8# jug of both 2400 and Unique for the same reasons. I shoot several calibers of handguns, and pistols, and wanted something I could load them all with. While neither will get me the "BEST" load for more than one maybe two, either WILL alloy me to load a wide range of bullet weights in them all.
So you will have to work up loads for YOUR pistol as was suggested. IT might be one, the other, or both which may actually work great in your pistol. Then you will find something else that determines which one is actually tops. Recoil, clean burning, smoke, flash, all come into play. If your just loading target practice loads pick one and go for it.
