Personally, I never use selection tools.  For me, they always end up needing the same amount of work / adjustment / correction as if I had simply used a layer mask.  So I'm with FrozenWaltDisney on this.

I've heard Vertus mask  is good, especially if you're dealing with hair, but I haven't tried it myself.

Perhaps, as some have suggested, you could be more specific as to what type of image you are working on?
