From all that I have been seeing and reading, the Pixel 3a seems to be solid generally. I'm curious about it, but 99 has one so he will probably be best for the personal experience.
Since you're not interested in Samsung and the Pixel series is still up there, I can really only think of Huawei but I haven't been following it enough to know, outside of the P20 being good in the camera. The Mates sound huge in size to me so I have glossed over that, I'll admit. I don't think the OnePlus 7 would be of interest but please correct me if I'm wrong.
