If I were picking between the two solely on track performance, I'd stick with the GY's. If you aren't an aggressive driver on the track (I am), you might not even overheat the MPSS tires. The MPSS would be a better daily driver tire, with occasional track use.
That being said, I went to order some MPSS tires for my '14 1LE, but they were on backorder, so I've ordered the BFG Rival tires in the same 285/35-20 size. So, I'll eventually have a third tire to compare with.

Interesting experience and having tracked with you I have no reason to doubt what you're saying Tony as I know you're a fantastic driver. However I've had the exact opposite experience with both sets of tires on my ZL1. I've over heated the GoodYears much faster than my MPSS. However I have since moved to the Yokohama Advan Neova AD08R's (305 on all corners) and while the grip is about the same as the GY's or MPSS's they seem to dissipate heat much better. However I'm still in the testing phase, I've only had them at two track events, Grand Sport and Texas World.
