If choosing (without a visit), I'd have to say someplace close to Sapporo. The main reason is for the weather/climate (it gets hot in Hokkaido, but not as bad as other places there, to my knowledge), and also because of the fact that there aren't as many insects (which creeps me out) that far up north compared to down south. I also like cold weather and I like getting bundled up for winter weather.
