For taxis, depends where you are and what other taxis you were booking. Compared to a London Black Cab, much better, compared to a licenced minicab, about the same but via an app instead of a phone call.

For Uber Eats though, I've had them claim that there is no expectation of food arriving hot. First few times I had delivery problems I got full refunds and the reputation was always "give it a go, worst case you can get a refund anyway". Now it's hard to even get in touch with support let alone get them to acknowledge an order issue, and refunds are almost unheard of.

Edit: I had forgotten about all the issues with sexual assaults by Uber drivers. They tried to downplay the issues, but ended up having to implement a lot of controls to understand who was driving the cars, in some markets they now have to be licenced, it's all changed a lot since the beginning because of how the service was actively dangerous compared to incumbents who were typically much more tightly regulated.
