I played the genesis 2 M for a while now...
Here's my comparison with H3Neo prov 39 deg with one layer of falco long:
spin: the genesis seems to have slightly more spin resp for me it is easier to generate spin with Genesis 2
speed: same for speed as for spin
In the high end, the H3 maybe has more power and spin, but my footwork is not good enough to generate these kind of shots more than 1-2 times per set. So for me, G2M is a real "easier to play with" version of the h3.
The only thing I'm not 100% happy with is that the rubber is noticably softer over all. For me, it is on the lowest limit.
Something like Genesis 2 hard would be very nice. But Stiga support told me that it is not planned yet (unless there are enough people who want to have that ;-)).
In comparison to MX-S the G2M feels more belanced to me. Sponge and rubber hardness fit better together and make the rubber more predictable.
