On an island I would say induction all the way.
We have ours on the island, we nearly went for gas having been gas devotees before this kitchen. Last minute change to induction and I am soooo glad we did.
It’s much safer - we have paperwork on the island a lot and it could be dangerous to use gas
The breeze from the kitchen door or skylight would mess with a gas flame
It’s sooooo much easier to clean, about 1000x easier. Honestly this is a good enough reason all by itself.
It’s safer for kids sitting at bar stools - no flame
You can use it as extra worksurface - so for example I can chop veg right next to my pan with the board on an unused area of hob, or I can lay plates on the hob ready to serve onto, without them being all wobbly and precarious like they would be on a gas hob.
Looks sleeker
Clever functions. Mine has a count down timer - I can set a ring to turn itself off after say 8 minutes. So I can go do the laundry and not overcook the veg. And a “keep warm” setting. And a “perfect fry” setting where it helps you brown without burning. Turns itself off if no pan is placed on it, or even with a pan on if nothing is touched for several hours.
Did I mention easier to clean??
The negative reviews of induction are usually about older or cheaper models where there isn’t much flexibility over where to put pans or where there isn’t enough power to create good quick heat. Get a high end Bosch or Siemens or equivalent and you’ll have all the power you need for wokking etc.
