I'm not sure exactly what you're asking. The BoV maps have all been determined to be suitable for competitive play in GenCon-like environments. There are a couple duds in there, IMHO, but most of the ones I've played on are very good. I recommend you do not start at the beginning. Just flip through, look for ones that speak to you, and try 'em out.
You may also like the Wargrounds of Scape project, which has
admitted a few maps.
Finally, you can go to the map threads subforum, and look for the threads for some of the more productive tournament-type mapmakers. Check out the threads for dignan, gamebear, and mad_wookiee, among others.
