One big thing is if you travel a lot, there is much greater chance that Uber will work when you get off the plane at a random destination then there is with Lyft.
Uber has better ETA to pickup, better Pool matching and routes and better prices in aggregate (i.e. If you always choose one TNC for all rides instead of shopping both apps every trip, you'll spend less on Uber).
Uber also have better minor features that you're less likely to appreciate until you need them like lost item recovery and spoitify integration.
