I'd try the 10mm torx socket first, it that doesn't work, drill it and use an easy out. It would be nice if you don't need to drill all the way thru the drain plug, but if you do, catch the first cup and discard, then catch the rest of the oil.

I was gonna suggest pulling the pan completely before you drill, but that would be just incredibly messy.

I always use a brand new, high quality drill for drilling and extracting. Done a few in the past year.
