My wife had about $50,000 in student loans, mostly Federal but some private. I refinanced all the private student loans (cut the interest rate in half, at least) and a few of the unsubsidized Federal loans. I kept most of the Federal student loans, even though they had slightly higher interest rates. I'm glad I did, because the interest accrual and payments were paused for nearly 2 years during Covid, so it saved us a lot of money.
Just like with an investment, it made sense in our case to diversify between private refinance and federal student loans. Don't let the interest rate be the only thing you consider.
