There's lots of disagreement here over the stability of VFP 6. I find it less stable than VFP 5.0, build 415 (the last release of 5.0). At the very least you will need to do complete regression testing if you upgrade to 6.0. You will probably have to work around some of the new bugs. There will be less documentation available on bugs than there is for 5.0 because it takes a while for MS to document everything in their knowledge base.

There's a patch for VFP 6.0 coming out, probably this spring. If you don't plan on releasing your application until well after that you may be able to take advantage of it. You should also take into consideration whether there are any features of VFP 6 that would be particularly useful for your project.
