2 Piece vs. 1 Piece Cast Aluminum Wheels

I am looking into buying Torq Thrust wheels for my '26T coupe. American Racing Wheels makes a TT D wheel that is my favorite. It is a 2 piece wheel. They also have a TT II wheel that is very close and is a 1 piece wheel. It is a little more modern looking. I like it but not quite as well as the D style. Pricing between the 2 styles is very close and the correct back spacings and widths are available in both styles.
My question is: Is there an inherent advantage either way to 1 piece wheels or 2 piece wheels? Should I let the 1pc vs 2pc sway my decision?

No, not at all.
Once the two piece are welded together there is, essentially, no difference. I have been running two piece wheels since I started building cars. never had an issue with any of them.
These are 2 piece Torq Thrusts and have been on the car for 5 years.

Now, if you really want something to stew about look at the old style Cragars. They were two piece and one half (the hoop) was steel and the spokes were cast aluminum... Never had an issue with those other then the chrome delaminating off the aluminum.

The 2-piece welded design just makes it a whole lot easier for the company to offer custom backspace solutions.

I've never seen 2-piece wheels that were broken just from normal use if even running over a curb or deep pothole....the only ones I've seen broken were in full -on high speed crashes.

I've had 2-piece welded Centerline Auto/Drags on my Nova since the early 1990's without a single problem.....and that's with 3.5" wide skinny's up front. 8.5's with 4.875" backspace on the rear.

Only issue to me is, you can easily spot the difference between the original one-piece-cast style that could have actually been on a car in the sixties - seventies, and the revised 2 pc. ones which became available as a tribute thing around 25 years ago, shortly after the one piece's were reintroduced after a long period of being discontinued. My wife and I were watching the movie Hidden Figures set in 1961 or so last night and at one point I said "look, there's a Chevy II with 1990s wheels!"...that is an instance where one-pieces should have been on the car, instead of the revised versions that were. Otherwise it's totally a matter of preference including that the two-pieces are an easier polish job, and what size you want as two-pieces are available in more.

Disclosure: We have two cars w/ one-pieces, each with the cast-texture spokes retained, one w/ TT "D"s from American Racing, the other Chinese straight-spoke copies as we wanted sixteens on that car and it's all that was available in the diameter at the time. For those I was kinda into the gennie sixties look and didn't want the newer ones.
