Opened up TF:Animated Voyager Optimus Prime ... it is sweet! It's better than the Deluxe version, but doesn't entirely blow it away.
Deluxe version is a great figure and has a very poseable robot mode, but lame alternate mode IMO. You can see the arms and hands when viewed from the back. Also has a great battle axe weapon.
Voyager version feels more sturdy, has a great, solid alternate mode & robot mode with everything hidden away in both modes. Maybe some slight kibble on the leg sides. Transformation is pretty easy (similar to G1 OP), but there is one auto-morph step where you push a button and the legs automatically spin and unwrap themselves to form Prime's legs - makes the toy feel very loose when you first try it. And even after the transformation, OP's waist is not really tight and stable, it tends to swivl, because of this auto-morph feature - could have done without this feature. Otherwise, it is awesome. Includes a gun for him that can shoot water, but his battle axe weapon looks lame compared to the Deluxe version.
Will post pics when I get a chance.
