I just picked up a 2017 American Pro Strat, I have two other Strat's to compare it to. I went with HSS and rosewood for this one.
I really like the new deep-C neck, with the narrow-tall frets, and 9.5 radius. For me, It has just the right amount of shoulder on the neck, to get clean and precise bends, consistently. Never frets out, it feels like less work than my other Strats, to achieve the same results.
The new pickups sound more articulate, or brighter, than my 2013 HSS, or '59 reissue SSS. I'm not sure if I'm completely satisfied with the new SC pickups, they aren't bad in any way, just different, more modern sounding somehow.
I use a Tremel-no on my other Strats to lock out the Trem, for the hardtail experience. I left the new one floating, it stays in tune fairly well.
Treble bleed circuit is nice, the satin neck back feels good too.
The deep-C neck, narrow-tall frets, might not suit everyone, but after getting a Tele with that combo, I had to have a Strat too.
