I did say I did not take inflation into account (a weakness in my numbers). As for the other components of the time value of money, I only showed the difference in nominal dollars paid, true. I feel intuitively that inflation is the piece that matters since the investment balances grew over the years but I might be wrong on that.
In addition to the link given by furwut above, here is another one by the same author that takes into account maxing out all retirement accounts.

I'm not sure either of the links really tries to account for a potentially higher tax rate on all tax payers in the future, even though it does a good job showing how each additional dollar earned has a different tax rate.
And there is also a ton of great information in both articles. Lots of stuff I did not think about or take into account in my OP spreadsheet.
There is a difference when you are maxing out all retirement accounts, as you will see in the above link. I think it defends (my takeaway) putting some dollars into a Roth 401K if you are maxing out all account types, but it's still complicated to know how much to put in the Roth 401K vs the Traditional 401K.
