Gogs,
It really depends on what you already have and what you need for the photos you're trying to shoot. If cost isn't an issue, you don't loose anything on the aperture by going with the 55-300. I haven't shot either of them, so can't speak to any quality difference between them. The extra reach from 200-300 can certainly come in handy when you want it though. The 300 has VR which is nice, but it is about twice the weight if that makes a difference.
