This is exactly my experience as well. Everyone at the local club wants nothing to do with anything other than Nittaku, because all the tournaments around here use them. So I oblige and crack them left and right. My brother and I train with DHS and they last forever. Hardly ever break one and when we do it's the tiniest little crack. I almost spilt a Nittaku completely in two with a good smash. I bought a sleeve of 6 Nittakus and they're all gone. The box of 10 DHS that I bought months earlier still has 8 left......and like you said they're cheaper.
Nittakus get shiny very fast and are less durable than the DHS, and they cost double-ish, so I prefer the DHS. The Bty A40s were pretty awful, but I just played a tournament with the Bty R40+ and those were fine, interchangeable with NP and DHS, but probably for an even higher price, idk.
