lightsaber yes, jedi.... really depends on the jedi.
sith most definitely. the only thing a guyver has in his favor is the regen factor.
i believe, that a guyver would be immune to the mind trick powers of force wielders, based on the fact that the guyver 0 was freed from the uranus telepathic control when bonded to his unit.
the reflexes of both sith and jedi are heightened depending on your training, and control of the force, while a guyver reflexes are heightened automatically to some extent at at base level. as an example, take sho shooting a bullet out of mid air that was fired, from what... like 6 feet? before it hit Tetsuro's head. sure its not the manga, but it follows the manga closely, and if memory serves, Tayuka (god i hope im spelling his name right) had a lot of say on the series.
so depending on the jedi, they may be able to avoid the guyvers abilities. that said, a crafty guyver *cough* G3 *cough* would be able to maneuver an opponent to where he could use a pressure cannon or even sonic buster, at a point in the fight where it would catch a Force wielder off guard.
and lets be honest... if droids and clones can kill jedi... a guyver should too.
