RE: Which do you prefer?
I use the glow driver that's in the power panel and hand start 99.99999% of the time. My starters mostly stay in the box that only goes to the pond when I'm running boats. I certainly could use the starters for planes, I've got 3 of them, but I've found them to be mostly unnecessary for plane engines. Using the power panel glow driver allows me to adjust the output, which results in more consistent hand starting. While I've heard the concern about wires getting in the way, all you need to do is route the glow connector wire under, then over the wing to keep it away from the prop or anything else.
