depends on the criteria you can call it the best. I mean it depends on what you are thinking is important for you, friend of mine use armory, and is ok with it, and as for me, I use electrum cause I don't like interface and it seems to me that electrum is easy to use.
True. Some prefers to have more features, some prefers not to have full blockchain, while some prefers maximum safety.
It is hard to say which wallet is the best, unless OP tells us what he wants and doesn't want.
