A lot of the Jedi ones don't seem too useful.
Quinlan Vos made one, for example, but it was too early in his career IMO. After he'd been through the dark and come out the other side, I'm sure he'd have lots of advice on the nature of the sides, but that was around when 66 hit and he went into hiding.
Who wants a holocron of Quinlan Vos's advice when he was tettering on the brink?
Hm, Arca Jeth's one of someone who has good force knowledge, but I don't like his philosophies or teaching style. He was snobbish about lightsabers and too proud of his force abilities.

Hah, yes, he speaks in that weird language *and* doesn't say much in it 🙂
When Krayt was talking to three holocrons, it was-
Bane: I only give knowledge to sith who follow my ways!
Andeddu: I'm secretly biding my time to get my body back!
Nihilus: *Random noises*
Darth Andeddu's has the problem that it tries to kill you or trick you into bringing it to his body so he can revive himself. Good knowledge but I'm not sure it's worth the effort, you know?
For another sith one, Darth Vectivus's. Aside from one useful force trick (the force phantoms), it's just him rambling on about business advice.
