I'm looking at new contract phones atm and considered these both. For me it comes down to repairibility, whether I can root to go google free using MicroG, no AMOLED as it will eventually burn in and a sweet spot in terms of screen size/phone size.Also, durability is important as I won't use cases.
The final criteria is the cringe factor which is illogical and personal. I just avoid buying things that I dislike even the tiniest thing about. Small things like the font of the word "honor" on Huawei Honor 8 or the word XPERIA on the back of Sony phones, the 1+ logo.
I've had my iPhone 5s for so long because I love everything about it.
Ok so, my biggest issues with-
Samsung S6- Poor repairibility. Samsung S7 - Too expensive Nexus 6p - Unnecessarily big and AMOLED but I like the design. Great camera. Excellent repairibility. Nexus 5x- Excellent repairibility. Great camera. Polycarbonate build is light but will be a step down from my iPhone 5s. Bothers me that it appears to have stereo speakers but does not. iPhone 6s/7 - Way too expensive and limited e.g. can't download more than 100mb on App Store over mobile data, no file system etc. I was thinking of getting a used 6s to go with my MacBook Air(for continuity features like airdrop, iMessage,FaceTime,handoff) before doing a complete 180 and deciding to sell the air and the 5s and go Android phone only.
Huawei P9- Am seriously considering this one. Great IPS screen, small size for 5.2 screen- barely larger than an iPhone 7. Excellent ifixit score- modular components, very good camera. I like the design a lot. Even parts like the camera island glass are available on eBay if I break something. Like the iPhone 6s it is secretly water resistant - there are videos on YouTube. The latest emui update looks good. The only gripe is that the power management apparently app apparently interferes with message notifications but this is fixed in the settings. No optical image stabilisation but video with eis looks good.
All the phones I mentioned have great cameras. If I didn't care as much, I would look at budget options which still have good cameras like Moto G, Vodafone Smart Ultra(cheap to unlock) etc.
