Time to jump the SAVE ship?

Out of curiosity, I was comparing income based plans. I used the fafsa loan repayment plan calculator and what I saw was sort of mind blowing. Under my current SAVE plan:

-Monthly payment: $908

-Total to be repaid: $121,199

-Forgiveness date: February 2035

-Forgiveness amount: $274,681

-Qualifying payments: 178/300

But if I switch to IBR:

-Monthly payment: ~$1800

-Total to be repaid: 114,678

-Forgiveness date: April 2030

-Forgiveness amount: $245,899

-Qualifying payments: 176/240

From what I understand, IBR forgiveness is not under the hammer and is separate from all other IDRs currently under injunction.

Assuming I can (grudgingly) afford the x2 payment amount of the IBR plan, shouldn’t I switch? Doesn’t this mean I could be done in 5 years and pay slightly less out of pocket overall and owe less tax for the amount forgiven?

What’s the downside? Feels like there’s a catch somewhere that I’m missing.

What would you do?
