IPhone 4S or LG Google Nexus 5?

Which phone do you think is better? I currently have a 4S and am considering selling it for a Nexus 5, but don't know if it's the right decision…

If you don't like your iPhone 4S and want to switch, switching to Nexus 5 is worth it.

My preference is for the Android phone, My wife switched from Galaxy S3 to iPhone 5 and is happy with it but I don't like to use it because it doesn't work as easily for me. If I used an iPhone for a few week instead of occasionally, I might get used to it.
You might like staying with iPhones since it works a bit differently than a windows or android phone unless you have used an android tablet like the Nexus 7 so would be used to how the Nexus 5 works.

Nexus 5 is right decision with lots of specifications, it gives you good experience than IPhone 4s.
