Can someone please tell me the differences between these 2 turbos other than the obvious......

Turbo 1: PTE5454-MFS
54mm inducer
3.0in inlet
2.0in outlet
54mm exducer
T3 .63 A/R
4 bolt 2.5in discharge

Turbo 2: PTE6262-CEA
62mm inducer
3.0in inlet
2.0in outlet
62mm exducer
T3 .63 A/R
4 bolt 2.5in discharge

I basically wanna know whats gonna be the biggest "driveabilty/performance" difference of the 2. the only difference in numbers is the wheel itself.
