Multi-asset Investments at AM vs. Equity Research at a Sell-side BB?

Hey guys,
It's unfortunate that this is my first post here but I wanted to see if you guys had any ideas about the above decision.
I currently have offers in a multi-asset investments team at an asset manager (think BlackRock, Fidelity etc.) and equity research at a sell-side bulge bracket (think Credit Suisse, Citi).
I'm currently leaning towards ER because it seems more structured and conducive to learning (I am currently a senior undergraduate). I worked with the sell-side ER team over the summer and generally enjoyed it. However, the multi-asset team at the asset manager interests me because it appears more quantitative and I'd like to be able to flex my statistical skills.
The Asset Management position is in NY, while the sell-side position is in Asia.
I'm looking forward to see what you have to say, and becoming a more active member here going forwards.
Thanks!
