Ok I apologize for my previous posts. I came across as pretentious and condescending, and for that, I'm truly sorry.
With that said, your reasons for going back to the 5s just don't make sense to me.
You said you dropped your phone and it scratched up really easy. Won't the iPhone do the same thing? They are both made out of aluminum so I would assume the same thing would happen on both devices.
Also your volume buttons were loose and you could have exchanged it for one that didn't have loose buttons.
Now the tiny screen real estate comment is probably what made me comment in such a condescending way. Check it out:
56% more screen real estate (probably a little less due to on screen buttons) compared to the iPhone 5s. How would anyone consider the iPhone screen only a little smaller?
The phone being disproportionate is subjective. If it's better for you then that's all that matters.
You can still not like the device for the reasons stated, it's your money. I just think for the reasons given, you aren't gaining anything more by going back to your iPhone. That's my opinion though and you are going to have yours.
I truly wish you the best and hope you enjoy whatever device you get in the future!
