Boutique REPE vs. REAM at global IB?

Hi all,

Trying to figure out which offer makes more sense from a long-term career perspective and opening doors within the REPE megafund space. For reference, background is in debt placement at JLL/CBRE/Eastdil.

1) Option 1 is a REPE/Debt shop (c.5-10bn FUM) with little/no recognition internationally but provides a great learning opportunity across different funds/strategies/etc.

2) Option 2 is RE Debt within the AM arm of an IB with a great reputation globally but a smaller team and FUM (c.0.7-2bn).

Both have a similar role/title/comp/hours/etc.

Any insights? Particularly curious about whether megafunds value experience and dealflow over name brands?

Thanks
