3 Things to add here:
1. You get source access to 6.8.2 and to the beta of 7 (and later version 7). They are both different products you don't have landscape editor etc for Version 7 for example.
2. They both have different toolsets and different licenses applied to them. You can decide yourself which you want to use.
See the PowerRender Forums, PR7 License board for more specific informations straight from its creator
3. The best part is that PR is a site source license ... not single user
