So, I've been lucky enough to have been gifted a new driver from my Dad (says he cant hit it, but I think his swing is more the issue). I'm getting rid of my old driver, but I'm not sure which shaft I should keep, or if there is even a difference.

The newer driver is a a 2 year old Burner (9.5 degrees), with a Matrix Ozik X-CON 4.8 stiff shaft. It is about an inch longer than the shaft on my current driver.

My current driver is an R9 (10.5 degrees), with a Fujikura Motore 75 TP Stiff shaft.

I'm getting rid of the R9, but want to make sure I have the better shaft set up on the Burner. Could anyone help me better understand my choice??
