Best Z97 motherboard?

[Jennings99]

I currently have an i7 4770K and GTX 770.
I want to upgrade my motherboard to overclock maintaining low temps.

I'm looking for a Z97 motherboard and not sure what ones are good?
I was looking towards -

Asus Z97-A Intel Z97
OR
MSI Z97-G45 GAMING 5

Of the two the Z97-A is very good, I went w/ the Z97 Hero (had the Z87), and it runs cooler and OCs better than the Z87 which was the #1 Z87 mobo, they've improved the A model also, have 5 builds on it and all have gone well and the clients are very happy with them
