Uber Eats vs Uber ATG

I have an offer from Uber Eats SF for a Data Scientist II position. However, I am more keen on the AI Scientist, Deep Learning/ML Specialist roles in Uber ATG. Can somebody evaluate the pros and cons of these two groups? (heard of re-orgs and instability in ATG recently).. I am looking to progress my research / ML career more as opposed to getting into product centric groups (e.g. uber eats). Background: ML PhD Recent Grad focusing on large scale ML, optimization
