Anybody can review Smash Up Half The Battle?

Hello Smash Up fans!

I'm interested in Smash Up Half the Battle factions, I'm planning to order from POD and since you can pick and choose the factions from there without buying the set, wondering if the full set is worth it. I fail to find a lot of review type of information (I saw the cards themselves, but sometimes it's hard to tell if the synergy is there without trying it out). Maybe somebody, who played with this expansion a few times, could share their thoughts on this set, what works, what does not, what good combos you have found with it, etc. Particularly interested in the AEG factios, seems fun enough on paper with unique minions. But for now, not sure if I should go with a shiny new thing, or go with Oops you did it again, as planned.
