Get another Core Prime or change to Grand Prime ?

[AppleUser]

My year old Core doesn't sound good to callers, but callers state it sounds much better through my bluetooth earpiece. I don't care about the warranty, if any. The reviews of the Grand Prime sound better and both phones are under $100.

Would you choose the Core Prime or Grand Prime, and why?

Thank you.

I have used both the Core Prime and Grand Prime.

I would recommend Grand Prime for the screen size (easy readability of email, web pages), decent size to carry around and the sound quality is good with or without a ear phone/bluetooth.
