Show the math

Both accounts invest the same nominal amount each year. The Roth uses after-tax dollars so withdrawals are tax-free. The Traditional defers tax now but withdrawals are taxed at your retirement rate.

Roth after-tax contribution = $7,000 × (1 − 22%) = $5,460 / yr compounded at 7% for 35 yrs = $819,480

Traditional pre-tax balance = $1,050,615 → after 22% withdrawal tax = $819,480

The breakeven retirement tax rate is 22% — if your retirement rate is above this, Roth wins; below it, Traditional wins. With a current rate of 22% and expected retirement rate of 22%, Roth is ahead by -$0.
