Haven't used Nugeon brand but I've put a lot of Bendix loaded calipers on. Over 100,000 miles, on Hondas, I put on loaded calipers (rebuilt calipers with Bendix best pads) . They go on real quick and last over 50,000 miles before they need pads again.
BMW sells a rebuild kit for the caliper and the guides. $25 a side but you get dirty and have to do a lot more work. I say go for the rebuilts. Nugeon also sells Axxis pads.
