I'm glad that you're happy with your purchase as I am with mine.
The reasons for me buying the BCA upper is to have a platform to try the 6.5 Grendel where price, price, and price are the primary criteria. I'm not much of an AR guy, only have a few of them that seldom get used. I had thought about buying an RAR Predator or Rancher, but the BCA upper was only $275.10 delivered, so it met my criteria better than the Ruger options. I hadn't intended to buy another lower, but for $126.25 delivered, the PSA unit was too cheap to pass on, so in the tradition of "stone soup" guns, I spent a little more money to get a little more. If it doesn't work out or I get bored with it, I can probably sell it for what I have into it or I can clean it, pack it, put it on a shelf and forget about it until I have to move it to wherever my Wife decides that we're going to live in retirement.
