Does one work better than the other or doesn't it matter?

--therefore a taper crimp die is not necessary as it is relatively new./QUOTE]
I guess it depends on your definition of new. I have been using taper crimp dies with 45 ACP and other auto pistol cartridges since 1980 when I started reloading.
Back then, all seater dies were machined with roll crimps. You either minimize belling so that no crimping is necessary. Or, you set the roll crimp to minimally crimp the case to remove the case mouth belling.
Both methods required lots of attention to detail so that the bullets were seated correctly and the cartridges chamber correctly. Most importantly, case length needs to be fairly consistent.
As said, the 45 ACP head spaces on the mouth, so a true roll crimp is not appropriate.
So, yes, you can load 45 ACP without a taper crimp.
In 1980, taper crimp dies were available but only as a special order from the manufacturers. In the eighties, Lee came out with a line of taper crimp dies that were readily available.
What is relatively new is the die manufacturers offering auto pistol seater dies with taper crimps instead of roll crimps. This, maybe started in the mid nineties or so.
I find taper crimping my 45 ACP makes loading it easier. I can increase the mouth belling a bit to make bullet seating easier, then remove the belling with the taper crimp. I taper crimp in a fourth step, a carry over from my loading in the eighties.
RCBS was doing it in the early 80's (81/82), if not sooner.What is relatively new is the die manufacturers offering auto pistol seater dies with taper crimps instead of roll crimps. This, maybe started in the mid nineties or so.

.45ACP headspaces on the casemouth, hence the need for a taper crimp. If you are using it in moonclips in a wheelgun I guess either would work.
