You're right, it isn't always better. But generally in a lot of problems these days we already have a load of generic methods for the implementations, and you just want to specify the end result. There's enough resources that we don't care how the thing is done, the engine will probably do it in an acceptable manner, so you save a lot of code just telling it what you want. It's really just a preference for convenience over control.
