I took a good long look at the USFA's when I sold my Cimarrons and ultimately bought Colts. The USFA's are very, very nice guns indeed. Even the lower priced Rodeo is a great gun. And of course, my Cimarron Ubertis were fine guns as well. I would have enjoyed shooting any of them.
It isn't about what's a better gun as they're all very nice and they'll all do the job, look good, hurl the lead, and be enjoyable to shoot. In the end what it's really all about is whether you want the genuine article, the Colt, or you don't care about the brand, the history, the charisma, etc.
When it comes to resale, if you ever have to sell your guns, you'll want to have Colts to sell. Of course, you won't really want to give up Colts either. It would be hard to give them up, but easier to give up a clone.
Some folks are just as happy saving some money and buying Ubertis or USFA's. For these folks, those are excellent choices. Other folks see something special in a Colt being a Colt and will make that choice. All the prospective buyer has to try to understand is which "camp" he or she falls in. It isn't something you analyse or compare engineering specs on, it's really more of a gut decision made from the heart, not the mind. Just my thinking, use it as you wish.
