Chicky's right about the wind! They prefer a bit of shade though they'll take more sun if they're in the ground as long as it's moisture retentive. Try to avoid a site where they'll get early morning sun if you get a lot of frosts. The leaves can get burned at the edges when it melts.
Terracotta will always look better than plastic, although some of the new resin pots are very impressive. A glazed pot will also set off an Acer well. If it's a specimen and you want it to look right, spend money on the container as well as the plant. It's the whole package that matters.
