RAcast for sure. HUcasts massive atp is good, but it saps from all the other stats. also, the RAcast can melee (thats what mine is doing now) as well as shoot well,but the hucast cant shoot very well. also, it means they can use gush weapons with better effect as they arent loosing health when they get hit!!!
also, RAcast has higher hp but this doesnt really come into play until about lvl 160. the atp difference is 250 at lvl 200, which isnt massive amounts and because of the HUcasts lack of ata they'll have to put that into the mag. that is, 80 lvl's of dex meaning that the atp diffference is now 100ish if the RAcsat puts 80 lvls into pow, and evp is slightly more on the HUcast. i would recommend RAcasts for the better ata+hp and slightly worse everything else. also, RAcasts look cooler!
