For a total CC army... BA or BT, most definatly, COdex: Space Marines doesn't allow for a FAST CHEAP GOOD TOTAL CC army. Grant Space Marines can do CC fine... Rhino+P. fist+2 assault weapons + frags = good assaulty unit.
However, said unit is expesnive, and frankly, one or two of these hike up your points REAL fast.
However, you can create a VERY balanced list, and, while head-to-head with assault armies marines can lose, had some infiltrating dev. squads (to deploy AFTER everyone else

) with 4 heavy bolters and the 'nids and their lovely Genestealers w/ extended carapace (I HATE IT!) are toast.
