All things being equal throughout your life, they both would yield the exact same tax effect. But due to income changes, tax bracket changes, inflation, etc. that won't hold true. My opinion is that taxes in 20-50 years will be higher than they are today, meaning the Roth should be the advantage, but a mix of the two helps hedge against these changes. And, as others have mentioned, Roth early in career and Traditional in later career helps take advantage of your tax brackets.
Seems like this topic gets brought up regularly, but something I never see addressed is the tax benefit of mixed distributions from Roth and Traditional in retirement. If you have a balance of both, you can pull from traditional up to the desired tax threshold, and then supplement the remainder of your expenses tax free with Roth, which reduces the taxes on your traditional balance.
