Dear lungimsam, The SV-8 has the same power output characteristics (by design) as the SONdelux. I have found them to be very slightly higher-drag (within the range of other SON hubs I've owned, though, and I've had several--I maintain five hub generators on currently-ridden machines) with the lights on, but no buzzier.
The "low speed cutout, flicker, and lights on after the wheel stops turning" criteria are largely a function of which LED light you choose and your definition of "low speed". With a Cyo or an Edelux, that cutout is just above strolling speed with either an SV-8 or a SONdelux. I like the Edelux II or its close relative, the Cyo Premium. What do you get with an Edelux that you don't with an SV-8 for the big upcharge? A pressure compensation system and possibly longer bearing life, nicer/lovely fit and finish, the option to have a wide-flange model, and made in Germany. I can't comment on aftermarket support one way or another, as I've only had one hub generator go bad (in 2002) in the fifteen years since I adopted the technology. Peter White fixed my heavily-used first-generation SON, and denied the warranty claim, though the problem was a known corrosion issue with the early SONs. I buy from others with more leverage with the distributor (PJW) rather than direct these days. You won't regret the choice either way.
