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.
