Longboard IMO. Bindings on a skateboard just seem silly. Once you get good on a longboard, you can do slides and kind of ride it like a snowboard. My friend has a cambered Loaded with dropthrough reverse kingpin Paris trucks and its pretty fun to bomb around. It's a good downhill board, very stable and it's easy to push because it's so low. I have just a cheapo Sector 9 complete (cost me like $150 or something) with regular trucks and it has more of that surfy, cruising feeling and it's a ton of fun to just ride around. It's kind of the equivalent of a reverse cambered snowboard compared to the Loaded.
Unless you want to only ride downhill, I'd stay away from the Freebords.
