A conventional deadlift is a is almost equal parts of both. Squat is more towards the knee extension end, and SLDL is more towards the hip extension end.
Now if you do squats and SLDL, YOU'VE GOT BOTH MOTIONS COVERED! Why does everyone think a conventional deadlift is so magical? Because you can handle the most weight?
As to partial deadlifts, yes you handle more weight but the erectors operate from a position of biomechanical advantage relative to the bottom position of a regular deadlift. From the pulling angle, much of the weight is transferred to the spine as compression forces rather than pulling on the erectors. This is because the angle between spine and hips is less than a right angle. The actual load born by the erectors is related to the sine of the angle, so the higher up you go the less load is on the erectors. Unless you are working on your grip (which you aren't because the dude says to use straps), I'd just do SLDL. As to the dude's argument of rack deads putting more stress on the upper back, well sure it does. But it's never gonna compare to a regular barbell row or chin for actually growing muscle.
Bottom line, I do think a form of deadlift is important but if you're doing squats, SLDL works best because it gets the hip extension movement to complement the quad work of squats.

casual... what may look right on paper doesn't necessarily translate to reality.
Squats and SLDL don't remotely hit my back the way deads do.
