From using my Link over the past week, here's what I can say:
Putting - Doesn't seem to glide as much as my D line P2's. It's also more stable than any plastic variant I've used of a P2. Compared to the P1x, it's shallower and much more stable. Compared to a P3X, it is slightly deeper than the P3X by a slightest bit. It's not quite as stable as a P3X.
Throwing - I haven't ripped it to really test its range, so I can't comment on that or its glide. I will say that the soft version is the ultimate shorter approach disc that I've been missing. I like that I can put it on a hyzer and get it around any trees that might be in my way and it will hold it. Thrown flat with a little bit of snap, it goes laser straight and has a slight fade at the end. The soft plastic lets the disc quickly nestle to the ground whenever it makes contact.
The hard version of this plastic is similar to the Classic plastic that you see in the Dynamic putters. Stiff, rigid, but very grippy.
The soft version of this plastic is similar to the Classic Blend plastic that you see in the Dynamic putters. Fairly rigid, but flexible. Same great grip. Probably most comparable to X line if you only know the Discmania line of plastics.
