MX-P 50 deg vs MX-S what is the difference? which one is "better"?

Hi Guys I need Advice for a new BH Rubber. My Setup so far was a Donic WSC with a MX-P on the FH and BH Rasant Grip. But now I need to change the Rasant Grip, because it is wearing off really fast. I'm playing mostly blocks and I do play topspin on the serve but then mostly punchblocks...
