I don't migrate, I just go back n forth between my 5s and Note 3. I would get bored too easily if I just had one platform to play around in so I definitely understand your reasons for going back to the iPhone. Eventually though, you'll get bored again and the cycle will continue to repeat itself.
I would suggest being a dual user. You get the best of both worlds. Preferably Android phone/iOS tablet combo to start out.
This is exactly what I do !!!

Wasn't the note 3 great on battery life?
Battery life on the note is rediculous!! ....in a good way
If I were given the option to keep just one device, it'd be the Note 3
