I currently sue A6 commercial and plan on moving to the A7 commercial version soon as well. PRO is currently out of my reach at this time. My question has to do with how they both render differently. Would the type of game, or level design, determine which commercial version i would want to use?? Can A7 COM render indoor levels as well as A6 COM?

It can render it similar. But the compiler differs. You dont have BSP anymore in the com edition. And there are still some issues with compiling a level and shadows.

So it can change your work-flow drastically.

Maybe you should check the trial version first.
