LO AM Credit Research or LO AM Quantitative Research for SA?

Current junior here. My end goal is to become a portfolio manager of a mutual fund/potentially a HF, so ideally I would want to skip IB. Pros and Cons for each:

Credit Research at LO AM:

Pros:

• Solid (at least according to WSO) buy-side shop within the fixed income investing sphere. Not a PIMCO but there are already so few FI investing SA positions to begin with. Large ($100b+) AUM.
• NYC
• I've had a background in doing fixed-income pitches in investing competitions and FI investing really interests me a lot. I much prefer fixed income investing towards equity investing.
• Exit ops are apparently strong; solid b-school placement as well as exits into prominent credit shops.

Cons:

• Lower pay
• No point in staying past 3+ years since no one ever leaves
• Less "prestigious"/well-regarded than QR option.

Quantitative Research at LO AM:

Pros:

• SA'ed here this past summer, absolutely love the culture and the people. (I was in a different area of the firm)
• Incredible educational opportunities in terms of the internship program (speaking from firsthand experience)
• One of the top names within LO AM (think Fidelity, Wellington, Blackrock, etc.).

Cons:

• Not based in NYC (and I kind of want to be in NYC as a young professional)
• Sense that I'm not smart enough for the job. I bombed all my quant trading/research interviews with the market makers (Citadel, Jane Street, IMC, etc), which really discouraged me and made me question if I'm fit for this type of role and career.
• Would not be FI focused.
• Is it worth doing two summers at the same place? Or is it better to try another firm for a summer and if I really want to come back full time?

Obviously I'd be happy with both opportunities, but considering my career goals, does anyone have any thoughts? Thank you so much!
