Since this is my idea, I reckon it'd be appropriate that I give my opinion on it...

Alex is a rather brutal shapeshifter IMO, and he is quick when it comes to taking down his enemies and in a variety of ways too. Despite his experience though, Alex has never really battled against alien threats (as opposed to zombies and stuff) unlike Hal. Hal also has one other advantage that he brings to the fight - while Alex can leap into the air, it may not be high enough to catch Hal when he is busy flying through the air and his shapeshifting abilities can reach a certain length or so (unlike Hal who can use his ring to make objects reach further distances).

It is for those reasons above that I vote Hal to be the winner of this battle.
