I haven't used the Vaporstar, but I can tell you that 'rich' or 'fat' hits mean (for most of us) a lot of vapor and not a lot of air. I don't know if there's much, if any, difference in the two glass pipes/bongs, but I'd go with the tube type over the bubble. There's less space for air storage, so it seems like you'd get less air in your hits. Looks like less chance to accidentally break it too, with the more streamlined shape.
