I have reviewed the Bose 35, Sennheiser, and Sony MDR-1000X M1/WH-1000XM2. I find Sony's NC to be on par with Bose for both products, with better sound quality. A majority of people on this forum just flock to Bose but there are some real contenders on my market now. Granted, Boses are still a slight bit more comfortable, but due to my love for classical, I prefer a more accurate sound production (ie Sony), while Bose is a touch base heavy. Sennheiser have even better sound quality for some people, but NC is sub-par.
