Welcome to Vector Linux! I also spent a number of years going from one distro to another. Most I think are pretty good at least in some ways. Some are excellent. A few aren't so good. Vector Linux, however, is the perfect Linux for me, and that's why I've used it continuously for a few years now. I do have a spare partition on my main machine in which I occasionally install a different distro, just to see what the other people are doing. I've seen some really good stuff that way, but nothing comes close to Vector in terms of overall quality (in my experience). Also, as kc1di said there is an excellent community here, and that makes VL much better than anything else I've seen.
Good luck with everything!
