Big 4 Business Valuation vs. Bulge bracket Commercial banking

My original goal when in undergrad was corporate banking (good pay, somewhat work/life balance). I landed a job in commercial banking at a regional bank after graduating - loved the environment but the company was small so the deal size and complexity weren't where I wanted. So I decided to go back to get my master's, to try to get into corp banking again. During my time in grad school, I got experience with valuation works and grew some fondness for it. I currently have two options for next year's internship: business valuation at a Big 4 firm, or commercial banking at a bulge bracket. Both of my prior experiences were great but too short to know if I truly like one over another for my long-term career or not. If I choose commercial banking, I can try to move to corporate banking later on. Plus, commercial banking experience at a BB firm would be much different than a regional one. As for business valuation, I interviewed and liked the team I am going to work with, and a part of me does want to try and experience this opportunity. Could anyone with experience in either field can give me some color in this: as for long-term benefits (salary, bonuses, work/life balance) which one would be the best option?
