depends on what aspect you mean... the 8.8 is much more common of a diff, as it was used in damn near everything from the mid 80's to the late 90's... and dealerships stock spider/side gears for them still, for less than 100$... so in that aspect, i would say the 8.8 is better... but strength wise? absolutely the 9" is stronger
