I have a french oven, why get a braiser pan?

I own a Le Creuset French/Dutch oven, but I'm considering getting a Le Creuset braising pan also: http://ift.tt/1EPB6di

I understand the oven is great for large/tall braising and stocks, soups, chili and the like. I also understand that the braiser has a wide base and is good for smaller quantities.

Should I invest in a braiser? I'm an amateur, but really getting into cooking in a big way. Any advice would be appreciated (before I go spend my christmas monies)
