is jamais vu worth the xp?

[Jakuzi]

I'm just thinking that
you need to click 200 orbs to get any mileage out of it right?
and on top of that in that time if you'd just upped an actual skill you might be more likely to succeed more checks that give you more xp that you could level up with (encyclopedia or conceptualization for example)

[Du-Vu]

As long as you're still fairly early in the game, you will definitely click that many orbs, easily.

And like a lot of thoughts, it also gives you contextual bonuses, +1 one or more on various checks, including +12 on one Conceptualization check in particular. You need a few skills you're specialized in, but having a lot of thoughts will help you be even better at what you're good at and more well-rounded at what you're not. That's the metaphor but it's also the mechanical benefit.
