That poster is asking about a traditional 401K vs. Roth 401K - income limits don't come into play in this decision, so you should probably be going traditional in your 401K. And that poster only makes 53K / year gross - well under both the Roth IRA limit, and the limit for making deductible traditional IRA contributions.
On the IRA front, you've got 3 choices (most people think it is only 2 - Roth or Traditional, but there are 3 distinct possibilities):
1. Roth IRA - you qualify here this year, no question
2. Traditional IRA without deduction - you could also do this, but if you're not getting the deduction this year, the Roth IRA is better. When you make even more money in a few years, this is step one of a backdoor Roth IRA.
3. Traditional IRA with deduction - this you may not qualify for at your income, but if you do, it is probably the best choice. Your MAGI for this purpose needs to be below 60K to be able to contribute the full amount.
Form the Roth IRA limit posted, I gather you file single - is that the case? Because the limits are higher if you're married and filing jointly. Based on the info presented, and assuming you're single, option 3 (tIRA w/ deduction) is likely not an option, so the choice is between a Roth IRA (1) and a non-deductible traditional IRA (2). Roth IRA is objectively the better choice of those 2 - you pay taxes today, but don't pay them in the future ever vs. paying taxes today and also paying them in the future on earnings.
