KBRA Corp Govt Financial Bonds Ratings SA vs. Wells Fargo COO Risk SA – Which is Better for IB/S&T/front office in Long-Term?

I’m a junior choosing between two Summer 2026 offers and want to move into IB or S&T long-term.

1. KBRA – Corp, Financial, Govt Bond Ratings Summer Analyst (NYC)

Credit analysis, financial statement work, issuer reviews

Very relevant to fixed income, DCM, and IB

Comparatively lower pay

Have seen people go from KBRA → IB

2. Wells Fargo – Business Risk Control Management SA (Charlotte)

Operational/middle-office risk work

Bigger brand and higher pay

Not front-office aligned

I’ve already tentatively accepted (like 2 days ago) but may have to talk to the recruiter and politely reneg..

My question is:

For someone targeting IB/S&T, which is the better junior internship:
More relevant experience at KBRA or
A bigger-bank name in a non-FO risk role at Wells Fargo?

Would appreciate insight from anyone in IB, S&T, credit, or who moved from ratings/middle office.
