570s vs 6XX Bigger Brother?

Finally got a 570s out on a track, and it was beyond amazing! I was curious for 6xx owners, if you had a chance to drive/compare between the two? Does anyone know also if any other company allows track runs or rentals of another mclaren? Even the P1 would be amazing!

Thx in advance,
