I like 'em both, but we prefer CODA. CODA "builds your character from the ground up" just like ICON and all the ICON stuff, with a little work, ports over into CODA fine. They also have much better narrator tools in CODA's Narrator's Guide -- rules for ship, world, sector, alien, and creature building.
I'd suggest CODA, myself, though the product support seems lackluster -- if it even exists. I'd strongly suggest the ICON products for the Vulcans and Andorians, the Romulan set was good, too. Strongly suggest you pick up the Star Carts book that also recently came out (not a game product).
"War is an ugly thing but not the ugliest of things; the decayed and degraded state of moral and patriotic feelings which thinks that nothing is worth war is much worse. A man who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself."
John Stuart Mill
