Motorola atrix 2 or samsung galaxy s 2?

Im not a fan of asking these types of question but im not finding much on either of these handsets.

I assume its because they are relatively new.

I am going through amazon wireless with at&t to make my purchase.

I've always been an HTC guy but now It seems the Competition for them is strong these days plus ive read the Inspire has pretty bad reception and i need it here in the foothills.My Last HTC the fuze was the worst for reception.Since then ive been using a flip phone because it gets better reception than my old htc.

Most important to me is Reception

Thanks for any wisdom especially that of the folks with experience with both.
