Well, it's both, for different people, seemingly :)

I also like the understanding and solving something difficult, that rewards a really strong part of my brain. But I don't always like to spend 5 hours in doing so, especially when I'm doing that because of some other problem I want to solve. Then I just want it solved ideally.

But then other days I engage in problems that are hard because they are hard, and because I want to spend 5 hours thinking about, designing the perfect solution for it and so on.

Different moments call for different methods, and particularly people seem to widely favor different methods too, which makes sense.
