Ok I'll bite, what's the difference? Should I have said "you get an unbloated clean customizable experience that has the essence of something like a Nexus or Pixel"? I guess when I think of a pixel I just think of a mostly clean experience so that's what I was comparing it to in my head. In fact, I think the OP6 might be closer to a pure basic Android experience like you used to get with a Nexus than the Pixel anyway.
Yes, I think the Pixel software is starting to get some bloat to it. I don't need the assistant, I don't want to squeeze it, I don't need effing stickers in my camera because I'm not 12 and I don't give a rats butt about VR on a phone. So you'll have to forgive me if I don't think the Pixel experience is perfect and the best. But by most accounts I've read the OP software is a very nice lightly customizable experience.
