Torx is also one great beast of grip.

I agree with you on that point, you can put more tork with torx screws. But
robertson is beter for "ordinary" every-days use, while torx is more oriented
toward technical uses. At least, here in Canada.

I can imagine Robertson as practical, but unfortunately it's damn rare
here, so I can't know for sure. Robertson is easier to make than torx
and for Robertson you can make a perfect key by yourself (well, you
_can_ for torx too, but it's not so trivial).

Never saw it in my place, to tell the truth. First time I even heard about
it! So, it may be inexistant here...

Here the most common for wood screws is 'posidriv' , an enhancement of
phillips, secure if you use the good size key

Alan screws for metal (nothing wrong with a bent bit of metal :-).

Yes, but only to certain limit. Pozidriv won't be delivering even near
the torque torx does easily. The reason is also simple, while torx's
head is flat when looked from the side:

I agree but you don't want to give too much torque to a wood screw :-)

Depends. I've had problems with pz's when the wood is really tight. But
generally, yes, usually the situation is as you said ;).

Yes, a Canadian invention and arguably one of the best screwdriver types
that never got the international (or at least American) exposure it perhaps
deserves.
http://en.wikipedia.org/wiki/Robertson_screwdriver
It is one of the most common used here in Canada for everything from wood
screws to metal screws.
However they can strip hideously if you use the wrong size head or don't
seat it well as I found out quite often while building my deck...
