I’ve just given my third programming talk where I use only my IDE (integrated development environment) for live coding and no other presentation tool. I noticed the audiences were very pleased with these talks, and I think it’s correlated to using an IDE and not a slides program.
If you've ever watched one of André's talks, you know he gives good talks regardless of whether or not he's using an IDE. But he makes a good case for their use in general and goes in to great detail* on how to do it well.
*even explaining each individual editor setting and why they were selected
