HARP 2.0 refinance interest rates - Zillow Mortgage Advice

We have a 30 yr mortgage @5% interest plus PMI with 4 yrs into it.
Loan currently with Wells Fargo. Excellent credit and payment history.

We would like to refinance under HARP 2.0 which we do quality for. Should we go ahead with Wells Fargo (as they have approached us to refinance under HARP) or could we get a better rate somewhere else? Any one here? Since we can refinance under HARP only once, we want to make sure that we get the best option/rate for us.

Thanks!
