My first head uses the RC2. I've found it fast, solid and secure.
If your panning plans include stitched panoramas, forget both of those heads, step into something that uses Arca-Swiss compatible plates, there is almost unlimited flexibility with the Arcs-Swiss set up.
Want a nodal rail? Want an "L" bracket? Want a gimbal? You need Arca-Swiss.
Also, for accurate panning, you'll be wanting a leveling base or leveling post.
