Actually the induction heat up faster than gas. The gas hob flame directly onto pot but the heat also spread into kitchen. More wasted energy but still cheaper to operate than induction. The induction kitchen is cooler than the gas kitchen.

Me? I used induction for about 20 years. Replace hob once already, faulty. Why not repair? Model old already and it has been fixed twice too

If you want to use induction, then make sure wiring is designed for the hob. Well, I should call it stove. There are stove with 2, 3 or 4 hobs. Bear in mind that the PSU (Power Supply Unit) is usually only one. The PSU will supply the power to all hob units. So, max heating power can be different when using one hob or more than one hobs.

The disadvantage is like what others said that you need pots that is magnetic. Yes stainless steel can be magnetic but also can be nonmagnetic, depending on process when making one. The aluminum type has metal base. If you are into traditional cooking using clay pot, then you are out of luck.

Me? I used modular type. Instead of using the unit with 4 induction hobs, I used 1 unit with 2 induction and 1 unit with 2 ceramic hobs. So, I can use any type of pots. To be honest, I rarely use the ceramic side

Another reason for choosing modular type is that if 1 unit is faulty, I can still use the other unit because they have their own PSU
