If I am sitting I wear Schnee pack boots on stand. If I am walking a little and sitting or really wet I wear Muck boot. If I am on the move I wear leather lace up boots such as Danner, etc.

So it depends on your usage.

Socks are an important part of the equation as well: polyproplene sock liners and merino wool socks are a must if your hunting in cool temps. Also if your sitting for long periods unlace your boots and make sure you buy boots with lots of wiggle room in the toes.
