Odd differences between Lightsabers and Vibroswords

[Spren]

So I wanted to use some Vibroswords on my Marauder, and I've already tested that I can use all my abilities with 2 equipped, but I found some strange differences:

With the same campaign weapon hilts/mods/etc:
Vibrosword minimum damage was higher than Lightsaber minimum damage by 8.
Vibrosword maximum damage was lower than Lightsaber maximum damage by 8.
Vibrosword does kinetic damage, Lightsaber does energy damage.

However, the empty shells of both weapons have the same range.

I'm guessing that there isn't a DPS difference between the two, because the higher min will average with the lower max. And energy/kinetic are both mitigated by armor, and as far as I know, bosses don't have a strong resistance to one compared to the other.

Has anyone done any testing or have any more information to share on the subject?

Based on that, they should work effectively identically. I know in Beta most AC-based abilities couldn't be used with Vibroswords, but I'm pretty sure they changed that before release, so it's really just flavor at this point.
