Don't worry you're not the only one that's had a bit of information overload....
The suggestion above are good ones. I'm currently using the Blackwidow Ultimate which uses Cherry Blue switches. It's a good solid board. I'm yet to experience any of the issues that's been reported on here. There's a nice heft to it and has backlighting for my late night gaming sessions. I'm on the fence about the macro keys though... If it wasn't there I probably would even notice I didn't have it. But since it's there I'm consciously trying to make use of them. The only thing I wish it had was some kind of KRO which would come in handy for games like SC2 for you where you have to have multiple key presses for groupings and such. Razer's new Blackwidow Stealth does have 6KRO via USB and uses the more silent Cherry Brown switch. NKRO also one of the reasons why I'm currently toying with the idea of getting another Mech Keyboard and I'm eyeing the upcoming Ducky Shine's. It's one of the few other mech boards out there with backlighting along with the BWU. Is backlighting an important feature for you? If it is then you might want to look at that option. If not you can always look at Filco's range... They've just released their Multicam model thats more tilted towards gaming.
Good luck on choosing. There's a tonne of options out there and, like you, I'm kinda scratching my head trying to decide on the best mech board... There's just so many options and considerations when it comes to deciding.
Edit: Also as mentioned about the new Corsair range looks like a good option to but I'm not too sure about the red switches they're using.... Really likin' the design and look of their K60's... No backlighting though. Only on their K90's.
