Asus Maximus VI Hero vs Asus Maximus VI Formula

Legenda in Aeternum
Have any particular need for the water bloc on the mobo? Or any of other features integral to the Formula? i.e. WiFi and is/are they worth the extra $100? I've built on both and both are great mobos, I went with the Hero and don't regret it, had no plans and no need to LC mobo or anything else, WiFi adapters are cheap (good ones from $15-20).....I like the Hero enough I'm planning to get the VII version for a Z97 build, mobo already on the way ;)
