Pay off a student loan or save for emergency?

So I should be getting about 4k on my tax return this year. I'm thinking of using it to pay off 1 of my 8 student loans.

I'm asking for advice because I only have 5k in emergency savings. My household is currently stable.

I've been focusing on emergency savings by putting $700/mo in, and I know this tax refund would nearly double my savings, but it could also pay off 1 whole loan.

With the save plan going away, I'm seeing my payment could be over $500/mo. I don't currently have a payment, but I'm paying $350/mo. $160 of it goes straight to interest.

What do you guys think? Pay the loan off so my payment plan is less, or put it in savings?

For reference, this loan costs me $152/year in interest. In my savings account, that money would make me about $140/year.

Edit for more info: I need 24k to have 6 months of emergency funds, which will take me 3 years to get to at the current rate for savings.
