I think he has answered that elsewhere. Old thread on rpg.net, unfortunately I don't have the link.
As for GURPS, I once held it in high regard but that was before it became too bloated. It was called 'TFT'...The Fantasy Trip. That was before it, or Steve Jackson, whichever, got delusions of grandeur. I fear it will be hard to find anything with the mixture of resolution and elegance you seek. Me, I'll take elegance over resolution (at least resolution to the extent attempted by games like GURPS or HERO).
Just for the record, I don't think GURPS is a bad system, and I would play it...but I don't want to run it.
But then, I don't want to run most game systems.
