I agree with you, for >95% of projects most of the tools available to you have reasonable upside and downside. If you were equally skilled in all options, it more or less doesn't matter what you pick. There are definitely problems, and entire fields (like hardware) where you don't have much of a choice due to the performance demands. But if you're building a small company or website, for the most part the dogmatism around the tools you use are nonsense, and just get in the way of getting stuff done.
