A lot of time these two options go hand in hand. That said, a lot of the tools I use at work are built by myself or my team. I trust them, so "making it work" is enough for me, especially because I don't always have the time to understand everything 100%. If I'm doing something as a hobby, I try to understand it, because time isn't really a factor there, and that's the fun part, right?
