It's a personal tastes matter.
According a tip from @DeadMan: "My mod covers only vibroswords, IRoberts will also change vibroblades and vibro double-blades, so I say use his version. If you like my weapon skins more (look at screenshots) you can mix them - install my mod first, then his but do not overwrite conflicting files."
In my last Playthrough I did that, I installed first Vibrosword replacement pack 1.0 and after [TSL] Vibroweapons replacement pack retexture 1.0 (without overwrite files).
Don't worry asking. When I don't know something ...I ask
