Since Alan Scott is serious here, he's more likely to be fighting akin to how he battled against Mordru, the guy who can stomp the JSA with ease, own the most powerful magical beings in the DCU and still took some trouble to beat Alan Scott. Loki doesn't have that kind of magical might so if Alan fights Loki, he should be able to match him just fine. So Team 2 should take a solid majority due to being more versatile and powerful than Loki and Ronan.
I'd have to disagree. Ronan's versaility is at least comparable to Hal's and while he's weaker in raw power, he has the energy blast feats to suggest he could match Hal's blasts. Hal could probably win due to telepathy and speed.
Team 2 does win though. In the end of the day Alan just has far too much raw power for either of them to adequately handle.
