Blizzard VS Westwood

There's an interesting article on Blizzard VS Westwood at 1up. So which RTS developer do you think is better? Blizzard or Westwood?

EA bought Westwood and then liquidated the company. Many of the older Westwood developers stayed in Las Vegas and formed Petroglyph, while some of the newer ones moved on with EA and became part of EALA, which makes the current C&C games.

As for the topic, as much as I've enjoyed some of Blizzard's titles (i.e. Diablo), Westwood has given me more memories to cherish.
