I've had three, sold two because I upgraded cranks and wanted matching arms. I've had two warranty replacements on the gen 1 because of battery door issues but that's been fixed with the newer body style. I've also had two powertaps replaced under warranty and had a torque tube replaced outside of warranty, so they've been no more reliable. Also the older body sl, sl+ powertaps weren't all that, rubbish bearings, and I don't mean what's fitted I mean using tiny bearing races in the non drive side with practically no shielding so they need to be replaced constantly. Rubbish spoke bracing angles because of the massive hub shell with narrow flange spacing. So while they may give you numbers they don't build into very good wheels compared to a normal hub. You can add shit free hub body's and sealing to that list too.
Decent local service partners? Are you joking? Srm send away to Germany, power2max send away to Germany, powertap send to Paligap, get in the queue, wait for parts, argue about the bill and warranty cover. When I've had a problem with my stages, I've had a new one two days later.
