Well I'm quite happy with gas and I haven't experienced the problems mentioned here - if I turn my burners down to low they don't go out. I suspect the hob that was doing that needed attention from a service engineer. Lets bear in mind that the very great majority of the catering trade use gas top burners, and most chefs seem to be able to make a sauce without burning it!
As most people will do, if the lowest setting is a little too high for simmering, then it's easy enough to take the pan to the side of the burner rather than having it fully over it - cast iron, or pans with good heat transfer properties, will cope with that without a problem.
There is also always the option of a heat diffuser or a simmering mat:-

Or, if an extra cooking plate is needed, then there is also the option of a portable induction hob which could be used for simmering or as required.
BTW I don't live on stir-fry sesley - "wok burner" is just a name for a more powerful burner that can be used for any cooking where rapid or high heat is required.
If some form of electric appliance was the only option, then I would go for induction, but if gas is available, then I would choose that.
But if buying an induction hob (or anything else they make) I wouldn't buy Neff, because in my view their products are over rated and over priced - try talking to an independent service engineer about Neff!
Le Creuset cookware works well enough because it is cast iron, but any cast iron cookware will work just as well, and at a fraction of the cost. But then of course there isn't the same potential for name dropping.
I wouldn't recommend halogen hobs to anyone - I do have a halogen grill which is excellent - but then that's a different kettle of fish altogether.
A halogen hob that is: "slow to heat up" sounds strange to me - I wonder if that was faulty too - one of the problems with halogen hobs is that they can put out large amounts of heat which can cause instability because the pan or pot has to absorb and distribute the heat and so there is lag between turning up the heat and the transfer of heat to the food being cooked. If when the heat peaks within the food things are too hot, and the adjustment control is turned down, there is likely to be a lag in cooling, and so the temperature control goes up and down and the cook gets frustrated.
Using a cast iron pan with a non-reflective base and turning the heat to medium (rather than full on) to pre-heat the pan or pot should help to keep things stable. But I'm not making a case for halogen hobs, because I would go for gas every time.
I don't have an axe to grind about induction hobs, I just don't think they are any better than gas - they do cost more to purchase and the potential for things to go wrong is greater than with gas.
Manufactures like Neff make great play on 'carbon foot printing' when it suits their sales pitch - but perhaps they should provide a little data about the effect of a self-cleaning Neff ovens on the environment?
There is some consumer feedback about Neff ovens on this site, which is worth reading before parting with any money.
As for being safer for children to play with, I think that's a ridiculous angle anyway, because young children shouldn't be allowed anywhere near a hob that is being used, and a kitchen is not a safe place for young children to play in at any time.
As with most things, it comes down to weighing up the pros and cons, and handing over your money, and then discovering how good-a choice you have made. I always take into consideration the initial outlay, the actual and potential cost of maintenance, how well the item will do the job, and how long a piece of equipment is likely to last.
These days I’m happy to pay a little more if the after-sales service is good (such as Lakeland) and I always look for as long a warranty as is available.
If buying an induction hob, I would definitely look for a 5-year parts and labour on-site warranty with no charges tagged on for call-out, etc.
Apparently the latest idea is to have an induction plate that heats anywhere within the confines of the hob, rather than within zones, so perhaps that's worth looking out for if buying in the future.
