I had the Galaxy Nexus (Samsung) and the Nexus 6. I may have had the Nexus 4 or 5, I dont remember. I had a few HTC phones before that and the DROID by Moto before that as my original smart phone. The DROID was peak - I miss the slide out keyboard.

The nexus 4 was also really mediocre. Only partial 4g and poor battery life iirc.

The nexus 5 also by LG was bulls eye though. Except for the ceramic letters constantly falling off.
