Sorter folks definitely have an advantage in simpler lever issues in basic, compound lifts.
I'm 6'3", and I have to be very carefull when going heavy with deads, for example, but shorter guys don't have as far to travel because of shorter limbs, and have a far easier time lifting heavy, to my experinece.
I thought I was bad because I finally got to the 5 plate club in deads (500lbs) for 3 reps, and the next day I observed a guy about 5'5" doing sets of 10 at 425, and he didn't look too put out at all.
Back to the drawing board...
