Big 4 TAS vs MF PE Investor Relations?

Hey all,

If you were a sophomore with these two offers for Summer '19, and your end game was to leverage one for IB SA 2020, which would you pick and why?

1. B4 TAS: Valuations
2. MF PE: Investor Relations

Now at first I thought it was a clear cut: B4 TAS, as one would get experience building DCF's, researching comps, and exposure to the end of deals. However, I've heard from some that IR at a MF PE would also require valuation skills + would result in potentially more exposure to deals, as well as brand name going an extremely far way.
