Yeah, I like Spycraft action dice better than WotC action points, though I have to admit that now I'm actually getting more used to the Wotc version since I've seen them so much and I haven't been reading much Spycraft in a while.
I like the UA version of APs a little more than the d20M/Eberron version, but I think I prefer M&M's Hero Points to anything else. Very free-form, and very useful. Not to mention, villains get them, too...
