This is a decision that greatly impacts your bankroll, because late registration often means the blinds will eliminate you if you don't go all in! On the other hand, when you start the tournament, at least on GGPoker, you have the advantage that if you're bubbled before the payouts, you win your entry! That's a huge advantage and a great way to fill the guaranteed tournaments! When we register late before the close, we're forced to go all in to grow our stack, even if we want to stay in the tournament and make a rebuy.
