Product group at BB to IB at MM(Intern)

I am currently an Intern analyst at a large BB(JPM/MS/BofAML) in DCM/ECM type role and am feeling a bit burnt out. Should I take the offer at a MM(RBC/Macquarie/Wells/Nomura) in an IB capacity for the next term with only 2 weeks break?

Right now my resume is pretty good considering I come from a semi-target school and have the BB on my resume but due to my graduation date I missed out on the most recent recruiting season. Should I go back to school or join the IB group. I would be covering an industry I am very interested in.
