MSF or Big 4 Tax?

Hey guys, I wanted some advice on what you guys are thinking I should do in this situation:

I'm a senior studying Finance at a semi-target school. I have an offer to work in Tax at Big 4, however I've realized pretty late that I have more of an interest to work in Commercial Banking.

I was wondering if you guys think it's more beneficial to take the Big 4 offer and apply to new grad programs at BBs when the recruitment cycle starts again OR get a Masters in Finance?

I know that a lot of Universities are waiving the GRE/GMAT requirement so I think applying to MSF programs might not be too bad.
