Totally agree. One of the best discriminator questions I've found is to have a candidate talk about a technology they've used in the past, and then talk about the pros and cons of that tech, and also to compare that tech with a competing tech they're familiar with. Poor candidates say something like "it's all great!" or "it's all awful", which is almost never true. They're unable to go beyond a very surface level "I called this library and it worked" kind of analysis. Good candidates are able to compare and contrast the pros and cons of lots of underlying details.
