Starting a podcast with snowball or gtrack?

I’ll be starting a new podcast soon and I’m looking at buying a new USB mic. Some of my friends on plurk said that Samson is a good mic because of it’s dual line input recording but for some reason I like the snowball mic. I was recently interviewed about MyNC by a friend using the snowball mic and was happy with the outcome.

I don’t think I’ll buy a mic tonight at the local Samash but when it’s time I think I’ll go with the Samson gtrack over the snowball.

Your thoughts?
