I'd go with the 3w-5-2 if your players have better quality. Also, i'd check the form of your lesser quality (stars) players you're considering playing. Just because they have less stars, doesn't necessarily mean they're weaker players. Players quality is based upon attributes we can see (stars, stats) and attributes we don't see (hidden mode). The hidden mode is the confusing part, but explains why some players with 5/6/7 stars get frequent rating of "6", while a 4 star players gets frequent "7" and "8" ratings...
