Induction is faster than gas, safer, doesn’t heat up the kitchen, emits no combustion fumes, more energy efficient, you get a nice flat surface which is easy to keep clean ...
Since we went induction, more than 15 years ago, we’ve never looked back, still have a gas stove in our caravan but even there we added a portable induction single cooker.
You might have to replace some pans but most stainless and all cast iron will work and I can’t imagine that it’s cheaper to install gas than to replace some cookware.
The only benefit I see is with gas is that the gas stove will work if you have a power outage, other than that I really don’t see any reason to even consider gas. Even if gas is cheaper the total bill per month wont be much higher, maybe even lower if you don’t have to run the ac to cool down your kitchen.
So, for me, there is no real question.
