All you mention are great mobos, it often falls into what your budget is, The Z87-A is sort of my preferred entry level Z87 for high performance, has good cooling OCs well, etc, the Pro is better with a little higher quality components and add ons (like Wifi), then at the top the is the Z87 Hero (built for performance/gaming, and to be honest I figured the Z97 would be a little better, but it's quite a bit better + it has the upgrade options open for Devils Canyon K model CPUs and then on into Broadwell when it arrives
