What's the diff?

I can't make sense as to what the difference is between these two parts - http://www.mouser.com/index.cfm?handler=displayproduct&lstdispproductid=212461&e_categoryid=268&e_pcodeid=59509 and http://www.mouser.com/index.cfm?handler=displayproduct&lstdispproductid=302743&e_categoryid=268&e_pcodeid=59509 The data sheet is like Braile to me!  Any help is greatly appreciated -

ACP has less offset voltage, makes no difference in guitar effects.  Go with whatever's cheapest.
