I was also considering the 5 v 6a. I went with the 6a because of the chipset, basically. I believe the camera is the same for both phones, but with the AI computer trickery, the photos that can come out of the 6a are better than the 5 will ever do. Plus, with all the trade in promotions, the 6a can be significantly less expensive.Currently using a pixel 5 and it has been the only phone thus far that I have had longer than a year. I've always been a power user and have always bought the expensive intl. unlocked behemoths from Samsung ( Note and the S-series).
Main reason why I've kept the pixel 5 longer than usual is the size and weight - this phone feels amazing in the hand and is very light. Camera is good but can be very good with the different GCam mods.
WAs thinking to give the 6a a try since the size is perfect also but not sure if it's worth switching the 5 for that. What are the current best deals to switch if they still offer them ? The performance of the 5 is decent but the 6a has the upgraded chips so that's what making me consider switching
