Pretty good in my mind. HAd to do a little fudging if you wanted some of the stuff not converted over as far as gear goes, and you have to wing more of the RP bits as well since the system is geared more to combat than other things.
But it allowed for some good games: Group I was in a long time ago did quite a few caper style missions - IE: the bad guys from Die Hard, or Heat, and so on and so forth as well as the white hat merc roles in some backwater.
