I can't decide which is better, the square or the star? Which is less
likely to strip?

Torx/star provides more contact area between the bit and screw, has no
cam-out tendency, and is less likely to strip out... The risk of snapping
them off in hard woods (physically hard, not hardwoods vs. softwoods)
without predrilling goes up too! Ask me how I know that... ;~)
