How much is the loan? And if you don't mind, your income (will that be steady over the years or will you have significant increases) if you're married, have dependents, etc.
The answer is actually complicated. Yes, there is an added subsidy benefit for REPAYE. If you're taking advantage of this it means your payments are not covering the interest. Since they're not touching the principal, you're likely a candidate for forgiveness. Otherwise IBR, REPAYE, etc really wouldn't matter in that you should definitely be paying now than the minimum to pay down there loan as day as possible.
The estimator is helpful but as I tell people it's not for everybody. It's most helpful for the year you are in and is often highly inaccurate over the course of the loan. For example, the range of payments. Most people interpret this as set. It's not because each year it's determined by your income. So basically the calculation is based on what your income increase would be over that period, with significant annual raises. For many people like me, you could be on your plan for 5 years and your payments actually ended up being about the same. Suddenly, that amount
they estimated you'd pay goes overall way down and the above forgiven goes way up. So when it says your payments will be $200-$600 over the course of the loan, you really have to take into account if you'll be making enough at the end too be making $600 payments.
The second thing to take into account is your circumstances. IBR has an income cap ($50k). If you are on it and your income goes above that you can stay on it. But if you go on REPAYE and your income goes above it, you cannot later switch back. This is important because that brings up to marriage. If you're married it get married, REPAYE will always take into account both of your incomes (and also both of your federal student loans if you have any). IBR, will take only your income if you file married filing separately (which has it's own consequences, money-wise).
To switch from IBR to REPAYE requires one payment at the standard payment amount or a reduced payment as low as $5 (the amount is your choice). That payment doesn't count towards the required number of payments for loan forgiveness.
If you can provide more details, maybe I can provide an answer more specific for you. However, sometimes choosing between the two plans is just an almost impossible choice based on events that haven't happened yet.
