I'd like to open up the field a bit to include Eagles. I've decided that having language, (rather than an opposable thumb) to be the major criteria as to what "races" can be included in your topic.
I would choose to be an Eagle of the First Age. To be able to fly, an observer of all that is going on everywhere in Arda, messenger of Manwe, hero -- swooping in at last possible second to save the day (really gets the adrenalin going) -- all in one package would really make me happy.
