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

Personally, I came to like the square drives because I found them to be far
superior to a philips drive, but since I went to star drives, I don't think
I'll ever go back unless the screw I need does not come in star. Just watch
your drive tips. They last a long time but at some point they will start to
round and you'll want to replace them. Like I say though - they will last a
long time.
By "star" I assume you mean Torx??? They are good, but they will
strip a lot easier than the square "robertson" Takes a lot to wear or
damage a robertson driver to the point it will slip.

I find exactly the opposite. Torx (star) are much better. I find the
screws aren't nearly precise enough for the Robertson (or "square head
recess") to work as well as it should.
I guess there is a difference between the generic "square-drive" now
being sold in the USA and the original Canadian Robertson (or Scrulox)
screws and screwdrivers. I know I've seen a lot af really crappy
square drive screwdrivers recently, and a lot of REALLY crappy screws
of all types with Chinese lettering on the boxes.. And the difference
between pozi-drive, Reed and Prince (aka Freerson), and Philips screws
and drivers causes a LOT of problems because they look so similar but
are virtually incompatible.
