Stick with what you know when you want reliability. Want to build products fast? Use the tech stack you are familiar with. Want to improve your tech? Learn new things. Choosing one over the other is very scenario specific. If you use new tech for building something fast, you would be inefficient with time but you will learn. It's a trade-off really.
I kinda hate JavaScript, but I love Vue.js as to how easy it has improved my skill set to do frontend code. So, if I would have stuck with JavaScript, I would have done myself a disservice in the long run :)
