One coin that I have been watching recently that isn't listed is Florin Coin.

I personally like the coin because it adds transaction comments.  It seems (this is 100% my opinion, so if the coin fizzles and dies when the alt coins start dropping don't haunt me please) that the coins that offer something unique tend to do better over time. 

Again, this is just my opinion. I'm sure there are plenty of people who are cringing at the site of my response, but you are looking for what people think.
