If you're looking for something rather basic, look into the Pixel line. They are like Apple in that it's just native Android with no extra features and quickest updates. If you want to go with the masses, look into Samsung. Those are still bare on features, but they look fancy (the all glass bodies could be more easily broken, though).
If features are a concern then what would you like? That can help narrow things down more. Or you could do like I did and go all out with the LG V20. It has a removable battery, still uses a large LCD (AMOLED screens have some drawbacks), micro-sd card slot, IR Blaster, the best microphones, best manual photo and video controls, metal body, headphone jack with high end DAC, and probably more I'm forgetting offhand.
