I have two woodworking toolsets in my garage. The yellow-brand stuff is awesome to cut up 2x4s and shoot nails through them until you have a shed or a chicken coop or a deck or whatnot. Then, there's carefully honed chisels, vintage planes restored with love, and - a recent addition - some Japanese saws to craft small things with high precision. Nobody would debate that having different sets of tools here is somehow strange. I also have two "software development" mindsets. There's code that is heavily utilitarian and will see a couple of users at most, sometimes just one; I stopped writing it myself, the big box store is not "Home Depot" but "Anthropic" and the result is coarse but serviceable _for this purpose_. And then there's code that sees a lot of users, has to build trust, has to work all the time, and likely has some safety and compliance requirements. The equivalent of my Japanese saws and Swedish steel chisels is the wetware in our heads. Finicky to use, maybe, but irreplaceable.
