I'd go with the Sennheiser PX550 or the Sony WH1000XM2. I own the Sony MDR1000X and totally love it. The MDR1000X has the same hardware, noise cancellation and sound EQ as the newer model so I do have a good idea of how the Sony WH1000XM2 sounds, and I do not think the sound is thin, perhaps it was the specific content that you heard. In fact, I think sound is even thinner on the Bose QC35. But anyway, everyone's sound preference is different. One thing for sure though, I think the Sony is super versatile and sounds excellent for all types of music genres. I've played everything from rock, EDM, dubstep, drum 'n' bass, acoustic rock, live music, etc. and they all sound great on the Sony.
