IB or Co-investments/Secondaries PE?

Hey guys,

I did 2 years at a boutique IB and am now looking for opportunities in both IB and PE.

I am interested in exploring both options. But what would you guys recommend in this scenario:

1. Move to a slightly larger boutique IB analyst role
2. Move to a large ($50Bn+ AUM) analyst role in the co-investments/secondaries PE group

Context: Because I've been at a smaller IB, I don't have extensive modelling experience. So I feel as if a few more years of banking will help me. However, I do eventually want to go into buy-side. I'm definitely more interested in the direct PE role, but my interviewer at the PE group suggested that this could be a good way to get my feet wet in PE in general and that there have been cases where analysts switched over to the direct side.

In the future, I can see myself being interested in an MBA program as well, if that changes anything.

Am I pigeon-hole-ing myself by going into co-investments/secondaries group? What are the comps generally like for analysts in co-investments/secondaries? What skills do you get out of analyst roles at co-investments/secondaries group?
