XS Edge vs XS Grip

I prefer Euro-made shoes (Mammut, Sportiva, SCARPA) which all use the same 2 types of rubber: Vibram XS grip or XS Edge.

Beyond the obvious idea that one is "edgier" and one is "gripper" does anyone have some wisdom comparing the types of rubber, and when to choose one or the other?I noticed some shoes are actually available with either option for the sole.

I don't really want to hear suggestions for other types of shoe rubber, thanks though.

I have Katana Lace which has XS Edge and I also have Vapor V which has XS Grip2. Grip2 is definitely stickier and softer than XS Edge. Right now I am debating whether to resole the Katana Lace with XS Edge or move to XS Grip 2. Not many resolers offer XS Grip 2 so that complicates my picture too.
XS Edge defintely holds its edge in 80+F heat. I do not have experience with Grip2 at elevated temperatures so I can't say it deteriorates significantly or not.

XS Grip 2 is a much better rubber in my opinion. I have the xs edge on my TC Pros and hate it. Selling the TC Pros this week.
