In reality these programmers don't want to have the feeling they might have made the wrong choice when they used X instead of Y. The idea that they might have taken the poorer choice hurts so much that they need to defend their decision so heavily while in reality taking ReactJS or Vue.js is like ordering pizza or pasta. You usually don't want to have both at the same time. So you need to explain why pizza is better than pasta tonight. Only that you usually have to stick longer around with Vue.js or ReactJS once chosen. Enjoy your choice and solve real problems, but stop fighting about it, programmers. Pasta and pizza will always both win.
