I keep reading that these aftermarket clutches will be great if installed correctly...

By following instructions like those found on installuniversity.com, how can you possible install it incorrectly. It seems like you just bolt everything back up how it was, and I don't see how it could be done differently.

Mount the clutch disk the wrong way, like engine side to flywheel side, not torque the bolts to spec, not use a alinment tool. Just ones i can think of.

Lots of ways....

don't clean the flywheel/friction disc/pressure plate allowing contaminants to ruin the clutch
Improperly/under/over torque the flywheel or pressure plate.
Install a new pressure plate/friction disc on a non-resurfaced/non-flat flywheel
Drive a new clutch on bad hydraulics
Install a badly unbalanced pressure plate/flywheel combination (this can do way more than just screw the clutch up)
Don't break the clutch in properly after the install
