Unless you're doing actual income-producing work out of your kitchen, the vanishingly small time savings on faster heat or greater multitasking capability are nowhere near enough to justify the expense some of these people brag about. It's silly.
Well, yes and no. Is it going to make you money? Recoup costs? Be "worth it" in a measurable way? No, obviously. Once you have a stove that works (at both high AND steady low temperatures) and an oven that holds steady temperatures... everything else is preference and aesthetics, more or less. But that's true for a lot of things.
Look, there are people here who could never, ever be convinced that a used Fit or Civic would ever possibly meet their needs. There are people who spend 200$+ a month on clothing, make-up, and aesthetics, because it's important to them, and they're willing to work for that. There are people with expensive hobbies (fishing? Boats? firearms?) that bring them joy and that they're unwilling to give up. There are people who will insist that you will pry their housecleaner away from their house over their cold dead body. There are people who value travel, and budget and plan and make FIRE-related plans for that include current and post-retirement travel. And the thing is: as long as you have ONE indulgence (aka: not the full list I just gave), that you budget for it, that you're aware of what it costs and what you give up for it, and that you're aware of what it means for the time you're spending working... You're doing pretty ok, y'know?
For me: I drive a Fit, and, at the peak of my driving-too-much, do less than 7K miles/year. I enjoy the occasional travel, but for me, it's really not essential. I enjoy nice clothes that fit well, buy them, and fix/mend/maintain them so that the overall expense isn't that high. My hobby, though? Cooking. Think elaborate plans to build a multi-level smokehouse in the field behind the house. Smoked trout, anyone? Yeah. So... for me, a gas stove that can be used for a wok, or a double oven... THAT's appealing.
Everyone has their priorities. The point here isn't to avoid all expenses. It's to maximize the happiness-to-stuff ratio. :)
