Nobody (except people trying to put up a straw man) has ever said "better than an Otus". What Jim Kasson said is "much better than the comparably sized and priced Sony 55mm f1.8, and relatively close to the Otus".
Bernard correctly makes the point that it is a far more convenient lens than an Otus.
There are some applications where the convenience doesn't matter at all, and if you have such an application and a very high budget, the Otus is still the best ~50mm there is.
I'd never buy an Otus (or the Noct) due to size, weight and sealing. If I could afford one, I'd buy the two Nikkor primes and the 14-30 to go with my present 24-70, then add either a PC Nikkor or two or the 500mm PF - two exotics I'd love to have.
My next lens is certainly the 14-30, which I really want to have in hand before hiking season. The positive reviews of the 50 are causing to be much more interested in it than I usually am in primes that duplicate a good zoom I already own (I don't tend to do shallow DOF terribly often)
