It's miles better! Big characters tend to form split views - people who love them, but then those who can't stand them really can't stand them! As a result, with vote to evict, it's far more likely that people will bother to pick up their phones to vote for their eviction. And we're left with them gone, and a less entertaining house. Voting to save would counteract this problem, because fanbases of bigger BB personalities would vote to save them.
