It's not a "major difference", but a few subtle differences. There's an article[^] on CodeProject that highlights the differences. Enjoy :)

I don't think that both have been thought up simultaneously with a distinct idea "let's use A in circumstance one and B in circumstance two". You got a sledgehammer and a warhammer, both have similar uses but different advantages and disadvantages in different situations.
