I have a GWA2 and I really like it. It's my upgrade from my Gear Sport. But I got the GWA2 instead of the GWA because I can call and answer phone calls from my watch with bluetooth connection. I don't think the GWA could do that. Also, I like the speaker on the watch and my Gear Sport didn't have any. I think there is much difference between the 2 though except for the calling/answering ability and price. Hope that helps.
