Because of this, non-Roth plans are overwhelmingly beneficial to Mustachians - who will choose to save/invest all the tax savings to fully capture the difference.

I'm new to the forum, so I never considered the early retirement factor. I switched over from the boglehead forum where everyone wants to retire a multi-millionaire. However, I will still argue for the ROTH. Your today's income tax savings should come from maxing your 401K, 403b, or 459 which is triple what you'll get from the 5500 in an IRA.
Now, it really doesn't matter if your planning on retiring in the low brackets, and in a tax friendly state.
