I went down a similar path and even did my own testing. I was a regular Pro v-1 player who was dabbling with checking out the AVX so I hit a bunch of balls on a launch monitor. I hit 75-yd wedge shots, full 7-ions, and full drivers, recording launch angle, spin rate, and total carry on my ten best swings with each club and with each ball: Pro v1, AVX, and the Maxfli TourX.
AVX was a clear loser - in terms of iron spin and driver carry distance, but the Prov V1 and Maxfli were indistinguishable. Since then, I've switched back and forth between Pro V1 and Maxfli tourX and cannot tell a difference in all kinds of wind and turf conditions. I was worried that maybe heavy winds would impact its performance, but it really hasn't. I do think there is a slight difference in how they come off the putter, but I am not good enough to really blame that for my putting.
I've now been playing the Maxfli almost exclusively and will completely stick with it once my last sleeve of ProV1s is gone.
