What people are looking for when they complain about the non-crossguard laser-broadsword is not realism in the conventional sense so much as internal consistency. In-universe it has been established that lightsaber cuts through pretty much anything- even blast doors will eventually melt, though it will take a long time. So using Star Wars' own rules, there seems no advantage, but a very great liability to stick a bunch of lightdaggers on the hilt of your sword. (But still have the actual crossguard that attaches to the blade vulnerable to another lightsaber if the blades ever lock.)
To pull from Tolkien
And furthermore, if it is simply supposed to be Rule of Cool, for me it fails on that front as well, but maybe for others it does not.

I am all for entering a world that has all sorts of crazy rules. But those rules ought not contradict each other, or else they ought to have a very good reason for the exception, or the art of building a consistent Secondary World has failed....makes a Secondary world which your mind can enter. Inside it, what he relates is "true": it accords with the laws of that world. You therefore believe it, while you are, as it were, inside. The moment disbelief arises, the spell is broken; the magic, or rather art, has failed.
