Valle vs Daigo in their win/loss ratio against each other, I really don't know, if I have to run off the top of my head, Daigo has the edge here with more wins I believe.
However, please do take, that after Alpha 3 or 1998, Valle has not been the same dedicated player (meaning that he's prioritized himself to do other things more so then simply play SF every day after Alpha 3), where as during 96-98, nobody could touch the Prime Alex Valle. Even to this day, I still believe that had Valle of been given the entire stated amount of sets to play Daigo in alpha 3 during that 98 championship match he would have turned things around instead of having those Capcom rep's skewer the whole situation in favor of Daigo which was bs imo, yeah, Valle isn't bitter about it, but it still annoys me, although it really shouldn't. Again, I posted a few pages back that it was supposed to be Two different styles for the Championship, they were supposed to play Japanese Format first, which was a Single Two round Default match, in which Valle won, but they reps didn't do anything at this point.
The Second setup would be USA style which was to be a Best out of Seven match up, but they just gave Daigo the win after being up only 2-1. So to me, that's still bs on how the Reps of Capcom did that. Everyone should know that at the highest level of play when at this time, both Valle and Daigo were absolutely equal in skill and level, anything could have happened.
Daigo on the other hand has obviously stayed consistently with the competition of SF throughout the majority of the 2000+ era. While Valle Post-1998 has more to do with family, and work instead of SF, so thus at the current versions of themselves, Daigo is definitely better then Valle.
Again though, not to discount Alex because during his Prime when he competed against both Top USA and Japanese players he completely dominated everyone and lost only once to one player ever...and that was against Jeff Schaeffer (As stated during this youtube video about Alex and Alpha 2, however please don't think Jeff>Alex in A2, because even Jeff has said it over that Alex was way better then anyone in Alpha2).
Justin Wong in actuality contends much better against Daigo now then Valle, simply because Wong plays and practices SF more so then Valle (although Marn has posted in the IV Forums about a month back that Wong doesn't play IV or fighting games as much as he used too either as well anymore). Considering that every time Wong vs Daigo has gone down in SF:IV, it has always come down to the Final and Last set, so again Wong is better competition for Daigo.
So if you want my take on this, 96-98 Valle = Daigo (In playing Alpha 3 of course, no way anybody beats Valle in Alpha 2, and if I remember correctly Valle even annihilated the competition in Tekken 3, because I remember in an interview he said Alpha 2, Alpha 3, and Tekken 3 were his most played, played fighting games ever), however current Daigo> Current Valle, Daigo's tournament placings prove this notion.
Lmao at the Guile BandWagon, like I said, I'm not surprised. However within a few months you'll be able to separate the Real Guile players from the "I saw Daigo play Guile and he did good so I can probably do the same" Guile players soon enough. I encourage players who play Guile because they like his character and want to truly learn and master his fundamentals and gameplay, however if your simply choosing him because a big name player made him dominate then you will not succeed or go very far with him.
