USA rail is almost identical to Aristo rail, right down to tapped holes and screws needed for the joiners. Ties are not the same.
Code 332 brass, and fully compatible with Aristocraft right down to the joiners and screws/allen wrench.
I'm running a couple hundred feet of USA Trains track and see no problems whatsoever, I recently came across some Aristo track, the USA trains tie spacing is a little farther apart than the aristo (more like aristo's european track), I also have some used LGB track and they all work fine together - I even use the Bachman track mixed with the aristo and USA trains track on the indoor area of track, all work fine!!
I have 10 #6 switches on my layout. 8 are Aristo and now 2 are USA, both, in my opinion, are equal.
The USA is a BEAUTIFUL and RUGGED switch that includes the lights, but the "light/switch motor" part does look somewhat like something from American Flyer.

USA trains track is made in the same giant plant as Aristo track though it uses its own dies, machines, etc. I have heard good things about their switches. It was a bit cheaper for awhile but I do not know if that is still true. I believe St.Aubins carries it.
