I personally feel more comfrotable in a group, that way I can "hide" when I want to and let the others talk when I dont feel like it. If its face to face and I dont feel like talking to people or cant get the conversation going its really painful! When it comes to first meeting I never have a problem with this, can also give good and VERY false first impressions. But tying bonds with people and actually becoming a friend is impossible for me, so I like to meet people on a short basis, talk a little bit and meet again 4 weeks later..lol
