I switched ~8 years ago and wouldn't go back to gas. No buzzing sound although if you listen very carefully there is a faint 'thrum' when it is active.
Visual feedback is from a number (1..9) displayed per induction ring. There is also a per-hob 'h' when it is off but still considered hot. When you activate a hob you can start it at strength 4 (of 9) or 9 (full-on). Or 1 and keep pressing up or down buttons to the setting you want. I'm used to this now.
Cleanability is awesome. Because the whole surface is flat, unused rings can also be used as a heat-proof surface when you have lots of hot pans that would scorch a normal work-surface. I think it keep things warm (without sticking) better than gas because the heat is better distributed over the whole bottom of a pan.
Main downside is that it is useless in a power-cut.
