The nexus 6p, Moto X pure and Note 5 have same size screen
Currently ...
I have the S6 Edge +, Moto X Style, 6s + and the 6P myself.
My daily driver I change about once a fortnight, but always carry a secondary device which can be any of the others.
I haven't actually used my Edge + for more than a few weeks though tbh as I had intended to sell.
I was going to sell my edge + for the blackberry priv but it's still incredibly elusive here that I haven't found one for sale. So instead as I now have to pay for my iPad Pro that should arrive tomorrow I'll likely sell it and put it towards that.
Still going to keep an eye out for the priv though as it just stokes my interest. Or maybe lumia 950 XL, (for continuum) though my interest in Windows phones has subsided considerably since the 1520 & 930 but other than those two devices (priv & 950 XL) there's nothing else out there at moment I want to try.
