Saw Chain, Micro Chisel, Super Chisel, Super Guard, 404 or 3/8

So whats the best chain??? My family each has a preference to a particular type for our own personal reasons, My dad swears by Super Chisel(http://www.oregonchain.com/dv/detail_38_72lp.htm) for its smoothness and cutting speed, My brother likes the newer Super Guard (http://www.oregonchain.com/dv/detail_38_72CJCKCL.htm) for its performance and i prefer the durability of the Micro Chisel(http://www.oregonchain.com/dv/detail_404_27.htm) for it ability to handle iron bark and other species which collect dirt and sand in the bark.

That said each of us sharpens differently to our own preference and get around the same M3/chain, unless we are in the mountain iron bark areas and i will generally get a few more m3 from a chain to the others.
