i'd go for a company/developer name if the whole team had creative input for most of the games content.
if most of the game was envisioned by one person with everyone else only doing the practical work and giving feedback as to whether the ideas presented by the director are good or plausible, then i'd say to use the person's name.
personally, if i'm ever going to start making indie games, i'm most likely to do the latter considering most of the work being into them is going to be carried out by myself with the most assistance coming in the form of the music department.
