[Star Wars] Have any Jedi/Sith ever favored a physical blade/vibroblade over a lightsaber as their primary weapon?

Lightsabers obviously have their advantages: Being able to deflect blaster bolts and cut through pretty much anything is their biggest ones. 

However, lightsabers are a *terrible* stealth weapon. They light up wherever the user is trying to do something. I could understand why the Jedi would choose not to use them... Except during the clone wars where their primary opponent is droids. There were a very large number of stealth missions where it could have been very beneficial to not have an "I AM HERE" weapon.

Even more so, why wouldn't Sith assassins use them? There seem to be a good number of metals that are resistant to lightsabers (in legends at least). Cortosis, while first appearing legends, is cannon. There are also more examples with metals like Mandalorian Ore and Ultrachrome. And whatever metal is apparently plentiful enough for the thousands of droid bodyguards during the Clone Wars to use against lightsabers.

I know Darth Maul trained with one for some of his early history in legends. 

I assume they don't use them because they have draw backs as well.

Training - Lightsabers are pretty much weightless. The training required to use a weighted sword effectively when you could just use a lightsaber probably isn't worth it to most. It may not sound like enough of a difference, but it is.

Cutting power - The lightsabers heat allows it to cut through things much easier then someone with a blade could, and a Lightsaber automatically cauterizes wounds making it so you can't really leave a blood trail.


Fear - like the Storm Trooper armor behind white, a Red Saber just instills fear wherever it goes, allowing the users a little big of an edge.

 Portability - It's much easier to hide a lightsaber handle then an entire blade.
