Accept Corporate Banking offer?

I recently received an offer from a large-mid sized middle market bank (think RBC capital markets) for Corporate Banking SA 2020 in Chicago. For some context, you are assigned to an industry group and work in the same division as IB, with very similar compensation to their IB SA’s.

Unfortunately due to transferring schools and a school year internship, my graduation date is being pushed back 1 semester from June 2021 to December 2021. This means I very likely would not be eligible for the full time offer, as I had told them I would be graduating in June 2021 to have a shot, per advice on this forum. Because of this extension, 2020 will be like my sophomore summer internship, meaning I will still have one more junior SA internship in 2021. This means I will be recruiting for IB SA next spring, however, this is before my corporate Banking SA internship will even start, meaning I won’t be able to recruit at the same bank for IB that I have the corporate banking offer from. Unfortunately this is one of the top 4 banks kids at my school typically place.

So I am wanting your advice as to whether I should accept this offer for strong sophomore internship experience and good compensation (pays twice as much hourly as current internship) even though it means giving up a strong bank to recruit at (lots of alumni) next spring. The other option would be declining the offer and aim for an IB boutique internship since it is still early in that cycle. I have no other offers for 2020 currently since I’ve spent majority of time preparing for 2021 IB recruiting. Any advice would be appreciated.
