I guess overall Collies are more mellow.. though again I have a couple that would be bouncing off the walls if they were left inside with little exercise throughout the day... so they are still very active. Shelties are more excitable (based on the ones I have known and I have known A LOT).. and IMO are a bit more barky, though my Collies do their fair share of barking. I don't know, its hard to explain, but once you are around both breeds for a while it is so easy to notice how different they really are.
