Should I trade my galaxy s4 for an iPhone 5 or 5s?

I like my galaxy s4 but the main problems with this phone is the battery dies fast, I prefer Iphone keyboard and it's made of plastic.
I would like to go back to Iphone and was wondering if it was a good idea?
I had an iPhone 5 before and I felt like the battery life (with Wi-Fi) was so much better than the s4 and the phone was all around a better made device

Get Nokia and f*** all.
