Benefits of conical fermenters

I'm a new home brewer and was wondering what the benefits were to using a conical fermenter as opposed to a simple bucket with airlock?

you can dump your yeast and trub off the bottom of the fermenter. It combines primary and secondary fermentation in one vessel. personally i have noticed faster fermentations but i have no science to back that up.
Most importantly it has serious bling factor they look wicked cool.
You need a fridge to control fermentation temp with them though, i guess some could see that as a drawback, check mine out here http://hollisbrewco.blogspot.com/2011/09/brewery-tour.html
