Here are some pros and cons. Induction is what I'd choose b/c I love the fun + new + it wouldn't hurt resale. I like hoods, in wood to match cabinets not stainless etc. (whatever finish your cabinets are). I like the idea of downdraft but some people say they don't work and a really good quality kitchen fan is a must. http://theinductionsite.com/proandcon.shtml

Great article by j222b, I have been using electric since I know how to cook and it's fine until I got my hands on a portable induction unit. The only thing is you'll need pots and pans with specially designed base.

As far as hood, I also prefer a conventional hood above the cooktop instead of downdraft unless the cooktop is location on a kitchen island and you don't want to block the view.
