What types of employment opportunities are you looking at?
They are now both Intrawest resorts.
Steamboat is at a lower elevation and has a shorter season. It is the only game in town and that can be a plus or minus. With no crowds from the Front Range - you may not get work some days. Steamboat is a real town. Copper has a resort village but is a short bus ride away from Frisco. Two snowboard instructors at Steamboat just got selected for the newly selected 2008-2012 AASI Snowboard Demo Team. They are also AASI examiners. The clientele may tip instructors better at Steamboat.
Copper's terrain is higher, longer season, and the terrain is more challenging. You'll probably always find work due to the Front Range crowds - even in slower periods. There are some top AASI trainers/examiners at Copper. Looks like many Aussie's and Kiwi's aren't getting their visas this season so I think hiring will be wide open at both joints.
It's a toss-up for me. But with Copper, if things don't work out, there's Vail and the Summit resorts.
