product control opportunity

I am now working in Big 4 London as a audit associate. I have been already ACCA exam qualified, but still work for ACA qualification as requested. Now, I have a chance to break into a Top BB (like GS, MS, JP) finance department as a product controller associate (delta one trading). It is a experience hire. I only have one working experience in Big 4 but exam qualified (a rare case). Moreover, The interviewer told me that the company can sponsor me to do for CFA qualification for a better understanding of the product.

I have two options now, still stick into the audit and wait 2 more years to try to transfer to transaction service team to do the due diligence in London for 2 years. Then try to apply FO or other relevant jobs in Asia. Or I move to product control position to do 1-2 years to leverage my CV based on the brand name and associate position. The salary should be far more than my current big 4 salary. But how about the exit opportunity. Definitely no plan for a long period of this role. Maybe pursue a top MBA in 2-3 years and then pursue FO in Asia or other finance relevant roles.

Any suggestions welcomed. Thanks a lot!
