First, Welcome to the Forum
Prices and condition being the same or close, I too would be purchasing the Performance Center offering.
In my younger days, I stayed away from Performance Center revolvers mostly because of the price. Paying for college left me with very little in recreational money
After saving up and getting my first Performance Center firearm, I was hooked. There has been no turning back since my first one.
Now, decades later, I have many Performance Center offerings.
I want to agree with kas9412, The revolvers using the multi piece tensioned barrels are the most accurate Smith & Wesson 357s I have ever fired.
You have been looking at the L-frames. The revolver that kas9412 mentions is a N-frame Model 327 TRR8. It's frame is made from Scandium alloy. It weighs in like a 4" K-frame but performs well beyond your expectations in terms of accuracy
I have added a set of the old factory Combats to mine, but there are Many other wood choices. Here is a set of Hogue Tulipwood on my Model 610. I order the Hogues with no finger grooves. That configuration fits me better and looks' better as well
OK, all of that being said . . . . I am certain that you would be happy with eiter of the two revolvers you are currently looking at
