I liked the setting and plot in Resistance 1 and 2 better, but in everything else, Halo blows it out of the water.
Example: Resistance never stood a chance against CoD on the PS3, but not only does Halo 3 lead it most of the time, the weeks/months that CoD was on top (In users), Halo 3 came roaring back afterwards. Resistance (1 and 2) just don't have that sort of support from insomniac, but that's also partly due to them being best at making one off titles with no support required afterwards (Ratchet and Clank etc).
Also, I find the combat in Halo 3 to be more enjoyable and the AI smarter. That's just my personal experience though, so it won't be the same for everyone.
