The cloned clips will be linked, by default. You can change that behavior by holding CTRL while dragging, except I think that clips created by Step Sequencer will always be linked, regardless (this is from memory, so please try it, rather than accept it as known fact).
Also from memory, there may be an option to control that default behavior, except for SS clips.
I routinely rely on linked clips when dragging to a new track to layer, as edits in any one of them will affect all of them, automatically, which means there is no extra time required, it just works.
The only time I am NOT such a fan is when I have created a clip in Step Sequencer, then drag it out and want to edit only selected clips within that array of linked clips. I end up having to recreate the clips I want to edit, so that they are not part of the linked ones. I have not tried unlinking just those clips - I will try that today, as one of the things I am doing will result in this situation.
