5 bolt gives you the option for a internal wastegate

5 bolt has the internal wastegate option
i have also heard that the 4 bolt will make a little more power

The 5 bolt that most are talking about were originally from the Ford SVO, that was a top -mounted turbocharger. 5 bolt exhaust housings on bottom mounted manifolds are typically a bit more difficult to install (only because of that last bolt). It also positions the turbocharger a bit differently because of the flanging position.
