What advantage is there to using trailing vs. rising edge interrupts?

in the option_reg line you can

bit 6 INTEDG: Interrupt Edge Select bit
1 = Interrupt on rising edge of INT pin
0 = Interrupt on falling edge of INT pin

bit 4 T0SE: Timer0 Source Edge Select bit
1 = Increment on high-to-low transition on T0CKI pin
0 = Increment on low-to-high transition on T0CKI pin

So why would you use one over the other?

If there is something I should have read please send a link but nothing I've seen gives a reason for either.
