I've had both motorized and hand-crank. I much prefer a motorized one. I have terrible knees because of a sports injury. I get uncomfortable both sitting and standing for extended periods of time. A handcrank is a complete pain to switch between sitting and standing. If I'm adjusting, I feel compelled to be committed to a different position. With a motorized desk, I can switch pretty much on a whim. I can sit for a while, stand up for 5 or 10 minutes, then get right back in my chair.
