Not a heck of a lot of difference. The VSR-10 probably has more aftermarket parts available. Personally I like the looks of the AIAW more than the VSR. The VSR is also probably a lighter rifle.
Neither is a steller performer and both require a lot of time and money to turn into really effective sniper platforms.
I should also mention that if this is your first airsoft gun and you're actually planning on going to games, don't buy a sniper rifle. Sniping in airsoft is absolutly nothing like it is in movies or with real firearms. Stock, no sniper rifle really has any meaningful advantage over an AEG, and playing the role of a sniper (which should more accuretly be described as recon, not sniper) is very difficult, boring, and not action filled.
