With normal primes, AF-S is just quieter. It's certainly not faster than screwdriver AF on a high-end body. The big motor on the F100 and F5/F6 can really toss those little primes around (the 50G in fact AF's slower than a 50/1.4D on a high-end body).
As to them being old and not updated recently, for the most part the Nikon primes are of similar vintage to the Canon. For example both system's 35/2 designs dates to the late 80's, as do both systems 85/1.8's (And both have been updated physically but not optically). Canon does have an advantage in a couple places (Notably the 35L and 24L, and the 135L as well) but Nikon has advantages elsewhere (the Nikon 20/2.8 is both half the size of and significantly sharper than the Canon, the Nikon 105/2 greatly outperforms the Canon 100/2 optically, the Nikon PC-E lenses are better than the TS-E's, especially the 24). If you need really fast wides, Canon's your only option (although rumour has it that Sony will be adding a Zeiss fast/wide to go with the 35/1.4G, and it will work fine on a Maxxum 7 or 9).
