Those are the ones that shred aux belts for fun, sorry should have specified alloy instead of metal in the last post. I assume it's where the HDi engines produce more torque at a less even output from engines like the GTi6 where they are popular.
The 307 pulleys do have a rubber section, it's just not as well damped as the 306 version. Would be nice to compare them side by side on an identical setup over a few thousand miles, but i'll never have time enough to do that.
The tensioners are more expensive and more of a pita to fit than the pulley; in theory you're better off fitting a standard item of reasonable quality, but if you must buy silly cheap then a 307 one will do the job for much longer than the alternative, simply because there's less low-quality rubber to fall apart.
