Rogue / Psi Warrior, help me think out 2 weapon fighting vs dueling

[MarkVIIIMarc]

Hello, I know the answers aren't always clear cut. I'm working on a Rogue / Psi Warrior build and am considering going 2 weapon fighting.

2 Weapon Fighting positives I think are:
- bonus to attack damage with the second weapon attack.
- the more often I make a second attack the more often the character may get a sneak attack bonus.

2 Weapon Fighting negatives are
- the offhand attack uses a bonus action which usually I'll want to use for disengage

Dueling positives are
- Simple, one weapon, no bonus action, plus 2 to AC if I carry a shield.
- Simple plus 2 to damage rolls
- I can still make a second weapon attack but a less good one.

What are your thoughts and thanks in advance.

Dueling also lets you potentially have a free hand, something that people tend to underestimate. It's potentially extra good for you, since you can telekinetically pull things to your hand if they're free. You can also just pick up stuff normally, interact with the environment (pull a switch, lock a door), make thrown weapon attack and grapple.
