Which is better for 30-yr goal, life-cycle mutual funds or DIY portfolio?

Life-cycle mutual funds automatically adjust asset allocation as a goal approaches, while a do-it-yourself (DIY) portfolio lets investors decide how to allocate money across equity, debt and gold or silver ETFs, according to Livemint. For a 30-year goal, life-cycle funds may suit those seeking a hands-off approach, while DIY portfolios may suit investors who prefer greater flexibility, it added.
