I like the newer options of the pistol braces. While I haven't SBR'd anything just yet, the braces really wet my appetite for an SBR. Additionally, I want to SBR my UZI for a more historically accurate (even with the wood stock) look, which just can't be done with the pistol brace. As many said, the pistol braces are simply easier to travel with and I travel across a state line for a range I frequent, so there is that.
SBR won't disappear (even if I would love to see that NFA process dropped), but the newer pistol brace rage may very well help speed up the processing time for an SBR!
