I am still rocking my Asus Zenfone 2 (I have a review on it on here ; I am posting remotely so linking it ain't happening).
It is still a great phone. It is now updated to Marshmallow. You can find it on sale for 199 off and on. Plus you can find loads of cases for it so you can personalize it to your heart's content.
Or if you want newer check out the Asus Zenfone 3 Laser.
