The math here is blunt: every dollar Jordan puts into a Roth 401(k) this year gets taxed at 27%, but the engine projects that dollar gets withdrawn in retirement at roughly 8%. That's a 19-point spread working against the Roth choice, year after year. A $0 net worth difference sounds like a tie, but it isn't. It means the traditional route arrives at the same terminal wealth while leaving more cash in Jordan's pocket today.
Your current effective rate of ~27% (engine-computed) drops to ~8% in retirement. Traditional saves taxes now when your rate is highest. The Current strategy produces $0 more at retirement.
