If you are close to retirement and your tax bracket is likely to be lower in retirement, you probably shouldn’t convert, especially if conversion will push you into a higher bracket now. On the other hand, if you are far from retirement and are in a lower tax bracket now, you are very likely to come out well ahead with a Roth IRA. If your income is too high to allow you to take a tax deduction on a regular IRA but low enough to qualify for a Roth, then there is no question that a Roth is right for you, since your contribution is made after tax in any event.
