Best NPCs to play along with

[Althanis]

This is my first time playing through and I was wondering which NPCs would be the best to play through with.

 

I was planning to play with Kreia and Atton. But after reading through the guide (up to where I am) I found out that I've exhausted all the dialogues with Kreia and got every bonus she could give me and her influence won't matter anymore, so I was thinking about dumping her.

 

Im on my second planter now, Nar Shaada, after going to Dantoine first.

 

Is Visas a good choice? And will I get enough lightsabers to dual weild myself and to give to her? Im also playing as Light and she's dark, will it be a good idea to play with her?
