It depends on your Karma, Star Paladin Cross will only follow you if your Karma is "GOOD" where as charon will do what you tell him once you buy the contract, IMO I would take Charron OR wait it out with GOOD Karma and get Fawkes

I prefer Charon because his shotgun is very accurate and you don't need any specific karma to get him.

Charon has like the best shotgun in tghe game due to the fact that it has no spread were as paladin star cross has a really crappy laser pistol but star cross has like 205 more points of health so it depends on what you prefere because you can always give her another gun.

Out of the few times I used Charon he seemed better than star paladin cross in battle, but if you want a character who can take out a super mutant behemoth on his own then get good karma and recruit Fawkes.

dont get me as a bigot.. but I'd prefer Cross.... Dnno.. Dont just like the ghoul voice..

I would get Charon because he is harder to kill.

It depends cross is better for a low level because at low lvls charon kills enemies quickley and you wont get much xp but charon is stronger and you karma doesn't matter.

bigglescat: You must be ripping through the main quest if you reach the citadel at a low level.

I think it best to get charon in honor of the late michael jackson. because charon is also rotting
