The world loves a good showdown. Superman vs. Lex Luthor in the movies. The Redskins vs. the Cowboys on the football field. France vs. Germany on the other football field.

The Motley Fool now has its own world of showdowns playing out at its new investment research service, named CAPS. Here, you will find not only investor pitted against investor, but also Main Street vs. Wall Street. Yeah, this rivalry is bound to be a classic.

I was checking out my score in CAPS the other day and decided to have a look around the overall site. Two companies caught my eye: Denny's (NASDAQ:DENN), a restaurant stock I follow, and Build-A-Bear (NYSE:BBW), a stock in my CAPS portfolio that's near and dear to my heart -- I must also admit that I've spent quite a bit of money at its stores.

Both stocks have five-star ratings in CAPS, and most of the players rating them have overwhelmingly picked them to outperform the market -- the numbers are 66 out of 70 for Denny's and 24 of 26 for the Bear.

The scoop on Denny's is that it has valuable real estate; it's in the process of a turnaround; and the price is too good to pass up at current levels. For Build-A-Bear, participants look to strong sales during the Christmas holidays (a little short-termish if you ask me), a great concept with busy stores, and a decent valuation.

What does Wall Street say about these two? Sell Denny's and hold Build-A-Bear.

Oh, my goodness. We have a classic showdown in the making. Two can enter, but only one will leave. Wall Street frowns on these stocks while Main Street loves them. Who'll be correct? Time will tell, but I wouldn't bet against Main Street if I were you.

Get in the game and make your voice heard.
