Does anyone have a preference for drill driver bits, specifically

#2. I've been driving quite a few screws the last few days and I've gone
through a box of those damn Vermont American bits. Some screws seem better
than others, but overall the bit seems just a tad too small for most
screws. After about 10 screws the bit starts to get rounded off and the
screw heads start to look like the Star of David. I'm driving these into
spruce with a small pilot hole, so nothing too strenuous. I've had to
finish off quite a few screws by hand, as my screwdriver grips better and
my 14.4 drill is a little wimpy for the longer screws.

I don't know if it's the bits (likely), the screws or if my technique is a
contributing factor. I tried to drill out one of my Star or David screws
and all I did was melt the drill bit, so the screws are plenty tough. BTW,
be careful drilling screws out of Particle Board, almost had a nice little
fire going. I was sure relieved that I did not have to throw water on
it and swell up my Particle Board.
The Bosch bits sold at the blue borg seem to hold up pretty well for me.
