OT, but since this is one of the few areas my little brain can conjure up some ideas in, so what the heck…
In my opinion, it's much more about taxes.
(1) Liquidity: Roth IRA allows you to withdraw the contribution any time for any reason free of taxes and penalties. So if liquidity is a concern, like when you're young, Roth IRA makes sense.
(2) Where you are in your career. If you're young and don't make a lot of money, pay the tax now.
(3) Traditional IRA is really not a good idea. Note that the tax deduction for Traditional IRA phases out extremely quickly, think $100,000 for married couples. So that correlate nicely with point (2).
(4) Since Traditional IRA is so restrictive, let's use a Traditional 401k as point of reference. Most plans have piss poor investment options, mostly funds.
So I see my Traditional 401k as a safety net, money that I can't touch until I'm 60. I only contribute enough for full matching. The rest and majority of my money is in Roth IRA and brokerage accounts. I need the liquidity.
