VantageScore vs. FICO

I'm hearing reports that lenders are turning to VantageScore credit results vs. FICO scores, and consumers are getting turned down for loans because of it.
FICO -- Fair Issac Co. -- has had the market cornered for years. The new VantageScore is the result of the 3 Big credit reporting firms Equifax, Experian, and TransUnion banding together to roll out their own version that they can market to banks themselves.
I've written about this in past posts. It will be interesting over the next year to see how lending institutions embrase Vantage over FICO, and if there will be a backlash from angry loan applicants.
