Snapnames is way better. I use to use expirefish but it only registered a couple names that I wanted, but nothing special.. infact, the domains were available for 2 days before ExpireFish even registered them!. Expirefish now has a similar thing as to snapnames where you don't have to be a monthly member, you can pay a one time fee to monitor a domain. I do this as backup if I already have it snapped at snapnames.
