Induction is superior. Had a higher-end of the regular brands gas before and never going back. Water boils insanely fast -- definitely faster than even pro gas burners. Greatly reduces heat in the kitchen vs gas or conventional electric. I don't think anyone's mentioned the safety aspect -- if you take a pan off and forget to turn off the burner, it automatically turns off in about 10 seconds. And, of course, induction doesn't heat by conduction like gas or conventional electric, so the surface isn't as hot, and if you accidentally touch a long sleeve or an oven mitt, you aren't going to get burned as quickly or a fire.
Recommend looking at Consumer Reports for brand reliability. IIRC, Bosch dishwashers are highly rated and reliable, but less so with cooktops/ranges.
You will need induction cookware. I've found some is rated for induction but while it does work, the ferrous content must be just enough so that the burner "sees" it and will stay on. This causes noticeably slow heating. I think this is a fairly common consideration with non-stick cookware in particular. I suspect the one poster having slow heating issues has this problem. Cast iron heats up very quickly and on higher settings will get incredibly hot -- sometimes too hot if you have enamel coated (recommended to reduce scratching potential).
We found that 5 on induction is closer to 6 or 6.5 on many others. That said, the low settings are *very* low, if that matters to you for delicate tasks. Most won't allow all burners on highest settings simultaneously -- rarely been something we've come across and even then, was not an issue.
