Board vendors love to claim they've fixed ENIG's problems but don't believe
them.  We routinely see ENIG problems in our failure analysis work.  The
bottom line is that using ENIG will give assembly and reliability problems
sooner or later, regardless of your supplier.  Other than that, ENIG is a
delight to work with and every other finish has some assembly or reliability
drawbacks.
