That's not my experience. The dynamic range of our induction hob is phenomenal. We can boil water faster than anything else, and the low mode is just excellent for very low temperatures (you can leave it on just to stay warm). I just wish the buttons worked better!
I have yet to come across an induction unit that handles low temp settings well- even the best ones I've tried use low-frequency PWM to approximate lower temperatures, and you need to have enough thermal mass in your pan to smooth it out that rapid adjustments aren't possible in the way that with using gas is. If you can recommend a specific model, I'd like to take a look at it.
Yeah it certainly uses pwm with about a 1 second period, and most of our pans are a good weight. It's effective though. The hob is a fairly fancy neff one, but I wouldn't necessarily recommend it for other reasons (the low and boost buttons stopped working after <4 years).
