Lightsabers are really, really different from modern swords. They have weightless blades, will cut through their targets independent of velocity, and can be turned on and off fairly quickly.
In light of these differences, it seems silly to expect battles between two masters of the weapon to resemble duels between swordsmen of earth. It seems even sillier to expect them to resemble Hollywood sword fights full of clashing blades, kicks, flips, and villainous monologues.
Given the differences between them and swords, what would be the best way to duel with a pair of standard Star Wars-physics lightsabers?
Probably not like this.
