Tried them both recently along with head speed pro. The vcore was much more solid and had a better feel for me, not stiff like some say. Easy power and spin and control, good mix. My 2nd favorite racquet behind my vcore 97 pro 330g.
The prince feels much like my t100p (2015), just a little better in all areas. I tried many variations of the phantoms and tour racquets in the past year, this was one was the best all around me. Personal preference, but I just like the feel of the yonex vcore 98 and I hit a bigger serve.
Also, don't sleep on the head speed pro. Paint job is boring just like Djokovic, but by far the best racquet I've played from head in years.
