Oh man...this is going to be tough. I am torn between LAX and Beer Money.
On one hand, you got Homicide and Hernandez. While horrible on the mic, Homicide is, as a high-risk wrestler, exciting as hell (and, I don't care how dangerous the Vertebreaker/Cop Killah is; it is, in my opinion, the sickest move there is in professional wrestling). While also not so good on the mic (but a little better than Homicide), Hernandez is an extremely quick and agile big man (as strange as it seems, I can't help but see a little bit of Vader in Hernandez). Mark my words: in the coming years, Hernandez will emerge as someone very significant in the professional wrestling world. Also, he has the potential to become one of the greatest "big men" ever.
On the other hand, you have Robert Roode and James Storm. As much as some people loved America's Most Wanted, I think that Storm found himself a better partner in Roode. Not only can these guys put on a good match, but they are also funny as hell and can create chemistry with even the blandest of tag teams. For example, when Abyss and Matt Morgan show their faces on Impact!, you can sense that there is nothing but indifference in the Impact! Zone. However, Roode and Storm have done the impossible in their feud with Abyss and Morgan: by taking advantage of Abyss' naivete and making Morgan extremely angry (this is about the only thing he is good at doing) in the process, they have made them both amusing and worthwhile to watch outside of the ring (I don't mind Abyss in matches; I think Morgan sucks inside and outside of the ring, even though, to his credit, he has a wrestler's dream body and build).
In the end, I will have to vote for Beer Money. While I think that the members of LAX, as singles competitors, have brighter futures, no one (not even anyone in WWE) is currently as on top of their game as Beer Money is.
P.S. When did La Familia become Italian?
