Who are the best low-mid level Jedi Masters?

I'm talking Eeth Koth, Luminara Unduli, Adi Gallia etc.

Kyp Durron.

This is pretty broad, tbh.

There are thousands of Jedi Masters in the EU.

The Hero of Umbara?

Luminara, Qui Gon, Ki Adi Mundi.

Shaak Ti.

Shaak Ti/Ki-Adi Mundi is the cut off. Below those two

Meetra Surik seems to have potential for a low tier Jedi master, I can see her being close to Tholme level maybe slightly above

Qui Gon Jinn
