Music Man Sabre vs JP15

Hi,
I would like to ask you to help me to choose most versatile guitar. I want to buy the high-end guitar, but alas don’t have a chance to try it in the store. I understand that MM Sabre is new model, but any way I hope you can help me.

I like piezo on JP15, but I don’t know if its so important to have it, if I already have another guitar with piezo – Godin A6 Ultra.

I mostly play and sing at the same time – pop and rock music, sometimes blues and country.
So, I’m looking for versatile guitar to use it for my own concerts and concerts with my students.

Please, help with your advise!
