Buck Rogers every time.
Nobody calld Buck wearing a tight, white, 70's style lycra jump suit could ever be defeated in combat.Buck has the ability to floor up to 7 or 8 bad guys with just one poorly executed karate kick,and with his little buddy tweaky? to watch his back.I think Macgyver would soon realise he was out matched and take his exploding pine cones else-where. 
Guns don't kill people,Stormtroopers do.
