Which plan is best for me? Just graduated with my PhD! PSLF or just pay off 28k?

Wondering which plan would be best for me if I am pursuing PSLF? I am at 55/120 payments.

Current AGI is 78k and student loan debt is 28k.

Loan calculator says $459 for RAP and $290 for IBR.

Realistically, I could even consider just paying off my total balance in about 2 years if I just dump my money into it based on my current finances..

Thanks for any help you can offer!
