The biggest reason I didn’t go with satin black is because I felt like this is a wheel that when done in black kind of ‘fades into the tire’. Just not a fan of that look and might have gone with it if there was some color or visible contour break that made the wheel stand out more from the tire.
For hyper black, a few reasons - first the fact that I saw so many (not that the RSe10 itself is that unique). Second, seeing them in person, I thought they were amazing, but seemed like a nightmare to keep clean...I didn’t want a wheel that would look like crap a day or two after it was cleaned. Finally, I personally dig the rotors standing out from the wheels and the wheels standing out from the tire...the rotors blended a bit too much with the silver”ish” color I thought (being really nit-picky and purely my opinion).
The upside of the satin gun metallic for me is that they stand out just enough and are easy to maintain...the down side is even when clean, they don’t really look that much better than when they’re dirty (hence the ‘safe wheel’ comment).
Hope that helps, but you really can’t go wrong with any of the colors and from personal experience, the 30% discount Neuspeed will give you on replacement wheels is also a great incentive IMO.
