SA is just trying to play catch up in the AR game. I don't have feelings negative or positive about their rifle. I have one of their pistols and I like it. I like their M1A but I'm not sure I want another $1600 rifle just yet.
I'm not a brand loyalist, I go with the best buy for my money in the features that I want. If the SA offers it, I will consider it, as I will consider a Colt, S&W, and so on. Whichever seems to be the best match, is the firearm I'll get. Which ever one it would end up being, the trigger is going to get changed out unless it comes with a better trigger than standard AR already but it has to have the right pull weight as well.
