Merrell boots: 'Enuma' versus 'Moab'

I'm trying to choose between Merrell 'Moab' boots (rrp $249) and Merrell 'Enuma' boots (also rrp $249... but on sale for $99).
With similar appearance and specs, it seems that the Moab is the updated version of the Enuma. The Moab has a vibram sole and goretex waterproofing (instead of the generic sole and waterproofing used in the Enuma).
But is it worth paying $249 (for the vibram and goretex) instead of $99? I've googled it, and some folks complain about the Enuma's waterproofing giving out within a matter of months. But for all I know, the Moab's goretex waterproofing might be equally unreliable.
Anyone got any advice or comments?
