I have yet to use the new formula, but when the old M105 and PG are both used correctly and on a pad with very little cut, like LC white or Meg's 9006, I've always noticed a better cut with M105.. I have used M95 a lot more than M105 and that cuts better than PG as well... PG, when used with a rougher pad, like LC yellow, or even orange, does cut very well but leaves an 'ugly' surface due partly to the pad and partly to PG... that's obviously my opinion from my experience but I would easily give M95 11-12, M105 12 and PG 9 or so... as I mentioned in that thread with the polish chart, there needs to be a standard where each polish is compared to the next on the same paint and same pad... I've done that with nearly all polishes I use (most of both the Menzerna and Meg's line) and, again, M105 and 95 not only cut a bit more than PG, but finish down much much better... PG to me is a lot like M85
