To be honest, most of the main girls would be good choices for different reasons. Silica has that upbeat attitude that would keep anyone from becoming too melancholy, plus she's not a bad blade when it comes down to it. Her age and immaturity would be an issue, though. Asuna, as shown in canon, is quite the partner to have, since she's both skilled and driven to clear the game. She is a bit pushy, though, and very emotion-driven, which could become exhausting over time unless you're into that sort of thing. Lisbeth has her handy blacksmith skills, which would be an immense help any way you look at it, but she's very stubborn and somewhat confrontational.

My choice would be Argo. Not only does she have good general information from the get-go, but she also has that knack for getting the info she needs. Her overenthusiastic tendencies toward gathering as much field guide info as she can, and her tendency to gettilng into trouble because of it is a bit of a non-issue, really, since it can only help when grinding levels or skills, and it's bound to rustle up some primo gear.
