i have both, wife has propel and I have the PA, there are major differences in how your legs position when pedaling. I found the position of the pedals and the fwd/aft motion of the mirage drive to be comfortable on my knees. My wife and son prefer the position and motion of the pedals on the propel. Before you drop that kind of money, follow the advice on here " test drive them both "
Mariner sail let me try both models on the water, gave them both a lengthy spin. Comfort was the highest priority for me. Good Luck, both are awesome fishing machines.
