I've played with both (currently own a 3, used a friends 2.0 for the day)...2.0 felt great! The setup with a rotor and 68/45 felt great, gun is very light, and sound and kick were minimal. It kind of reminded me of a very soft victory...nice smooth shot, but just a little bit of a slight "pop" sound to the shot...nothing like an ego or a vic, but not like a luxe, gt, etc. I was in love with the 2.0! So I hunted down a Geo 3...so far I've only thrown a few pods through it (and I didn't have a 2.0 to compare side by side), but it seemed to shoot very smooth and very quiet...it'll be neat to try it out next to a few of the Luxes next time I play just to compare...but otherwise I'm very happy with the sound and feel...also the gun feels great in hand, the features are amazing as always for a Planet Gun, and it does seem lighter and smaller...I know the weight is shaved off from the previous model...it'll be neat to see it next to a 2.0 next time I'm out as well, to see the size difference if there is any really.
If you can swing it, you might as well go for a 3...they have all of the perks of the 2.0/2.1 and more...but for the sake of saving money, hunt down a good deal on a 2.0/2.1...right now with the arrival of the LV1, you should actually find some great deals from guys trying to dump their Geo's for LV1 cash.
Good luck, hope that helped!
