If you're retiring to the same state, it doesn't matter. If you're retiring to a different state, it only matters if it swings your income dramatically from your working career to your retired life.
The typical advice for choosing Roth vs. Traditional IRAs (and 401ks) is that barring odd tax rules, you should invest in a Traditional IRA if your effective retirement tax rate is less than your marginal working tax rate. When you're calculating both those numbers, you should include state and local income taxes as well as your federal income tax.
