Hello!

I'm new to SWTOR, and I'm having a lot of trouble choosing between shadow and assassin.

What class have better story, and better companions?

Probably the Assassin, the Jedi Shadow has a bad chapter1, although chapter 2 is better, and chapter 3 is decent.

The Assassin however has a chapter 3 that's been compared to "Disney Hearts" involving destroying creatures reminiscent to the "Heartless".

(I am actually quoting someone else here, so track down that thread and complain to them if you don't like the comparison)

Also the Jedi Consular/Shadow quest line isn't affected by Light/Dark decisions.

Depends:

Jedi consular is polite humble and kind(even on dark side)

Sith inqisator is: selfish arogant powerhungry manipulative(even on light side)

The question you shoud ask yourself do i want to help other's(jedi consular) or serve myself(sith inqisator)

Pretty much this.

If you're concerned about the mirror, it's pretty accurate. At least now they've fixed the activation times of certain abilities/animations for the shadow. Sin used to be able to execute things faster due to animation times, Not now.
