Looking for an Alternate Phone to use.

[Jordan jones]

Right now I use a nexus 4. I love my nexus 4. However I am interested in trying out another phone with a different OS. I am a android lover however I think will not hurt to try another OS. I plan on using the phone on my days off, I will still use my Nexus 4 primarily. I love Google Now and Wallet to much. If anyone with experience with another phone OS can chime in please do. I wanted a Google experience phone but it would be like using the same phone but with different hardware so it was a non starter.
