1) Do you like coping or innovating?
2) Bing or Google?
3) Ride sharing or Mobility platform?
4) No IPO plans or well defined IPO strategy
5) No annual refreshers vs good annual refreshers
6) Lyft credit vs Uber credits (yes, you can buy food with it's through ubereats)
7) US centric vs global
I think it's a simple choice overall but you need to do your own research about the team and see which one you like the most.
Clearly with Infra Uber needs a lot more work to support these massive businesses like Rides, Eats, Frieght, ATG, Jump etc
Work life balance is team dependent.
