That is like saying something like this:

I have a Pentium 166 computer that comes with a lot of extra software, and I also have a Pentium 2+ ghz machine without all the extra software, but with more advanced functionality and will save me a lot of time. Which do I choose.

My argument for you would be... do you use all those tools that the VS6 includes? Or are you just impressed by them? My guess is you don't want those extra tools to go to waste. Let them go... VB.Net is here to stay, and it would be a step back to go to VB6 if you already have VB.Net. Or, find time to use and learn both. You will find that you want the .net functionality over VB6....I am sure.
