I originally started off with Noel due to the whole Gunslinger motif. At first I thought it would be a problem due to certain characters in other fighting games that use projectiles tend to ruin things *coughMinacough* but overall she's not so bad. Eventually I sat down and played with a couple of friends and one of them (jokingly) said: "Noel is a nub character. I bet if you pick someone else up I could beat you." Secretly I picked up other characters but couldn't really get used to them (Still having some trouble using Tao up to this day actually). Then I finally settled with Bang after watching some tutorial vids online and learning about how useful his Guard Point is during Burning Heart. Because of this, I ended up using him more often than I used Noel thus making her a secondary.
Eventually my friend and I faced off again and now he hates Bang. Those were some good times.
