Gives you some info on the difference in essex and cut pile.

I personally wouldn't go with anything other than loop. It's a thousand times easier to vacuum and clean. I think essex is easier to clean than cut pile but if you wind up with the type that is difficult to clean, your floor will wind up looking like it's carpeted with a 70s bush after a while.
