With all due respect, but this is utter bs. I've played both G-1 and the Tronix ACC (still do...). Neither the G-1 or the ACC are sticky (i. e. tacky). Grippy, yes, very grippy in fact. But if the topsheet of the ACC would be sticky/tacky, you would be able to press the racket with the Tronix ACC-topsheet onto the ball and lift the ball up. You can't do that with the ACC, not even for a fraction of a second.
The Tronix ACC also doesn't feel harder overall compared to the G-1, even though they have the same sponge hardness at 47.5°. The ACC noticeably feels softer than the G-1 (or T05 for that matter), because
a) the topsheet of the G-1 feels "tougher", harder, because the rubber compound used for the topsheet of G-1 seems to be of a harder nature and also because a different pimple structure is likely used and
b) the sponge of the ACC has larger pores (see Matt's comment) than the G-1, which has rather tiny pores, resulting in a slightly harder and kind of "linear" feel for the G-1, whereas the ACC feels "bouncier" than the G-1.
The Tronix ACC is (therefore) also not a so called hybrid. It's a regular ESN tensor, albeit a very good (and perhaps underrated) one.
