Both of these armies are mech. However the second one has very little in the way of anti-tank, except for the wraithguard (short range and are one shot deals, since the turn they leave their tanks, they get starcannoned to death), and the pulse lasers (which both armies have), whereas the first list has 3 extra linked brightlances. Given the speed of the armies, Recon won't be an issue. Both armies can get anything that can survive to the enemy zone, since they're both fast.
The wraithlords can be downed easily by scorpions (space marines average losing 5 men in a tactical with a veteran seargeant with powerfist, when they get charged. Exarches have higher initiative and WS and would charge). Battle also last long enough that most threats to the scorpions would be cleared by the time they got out of cc and most of the time they get out after 4 cc rounds, anyway, so they can just jump back in a transport on the next movement phase.
Neither sets of warp spiders will survive for long, because of mobile starcannons
Vypers and warwalkers will probably spend more time surviving and less time shooting. However, once the wave serpents are down, they have easy ways to slaughter the enemy.
If the Beta farseer decides to use that spear, or go out into the opening, it'll get starcannoned to death by starcannons at point blank range, or simply charged.
In summary, what will probably survive for most of the battle:
Alpha:
2 wave serpents with their cargos (1 would die, probably given inferior firepower of Beta) (units inside are fairly expensive scoring units
2 falcons (190 points)
Beta
3 Falcons with their cargo (assuming they aren't used)
Almost everything else is either fragile, or 1 of a set of high priority targets. Also, if there's time, the falcons in Alpha can pick up wounded aspect squads and make them virtually imprevious to fire.
In general, given that fact that armor is really irrelevant in this battle, most of it will be spent in cc or in vehicles. Starcannons are only useful at taking advantage of the enemy's mistakes and short range weapons are too exposing (they allow mass starcannoning, so the falcons and wave serpents will be the major forces in the battle).
So I vote Alpha, but that would be a really wierd battle
EDIT: oh yeah, and the Beta player is wrong in his explanations. Wraithcannons don't autoglance on 2 and penetrate on 6. That's haywire grenades. Wraithcannons glance on 4 and penetrate on 5-6, though of course, those'd be converted to glances against this Alpha army.
EDIT:EDIT: Oh yeah, and I vote alpha for fluff, since beta seems to be tailored to beat marines, with all those survivable starcannons and falcons, whereas alpha has a much more balanced list, fragile gun platforms and mixed aggressive aspect warriors
