Actually...
I rather like the metal Space Marine Terminators, and their Chaos equivalents. They look exactly how someone armor weighing a ton should look... slow and solid. If you start sticking them in all sorts of dynamic poses, it sort of defeats the look that I believe Jes Goodwin was going for.
However, now that Jes is heading up the plastics division at GW, we\'re seeing less and less of his sculpting prowess. I believe that Juan Diaz is responsible for the new Grey Knights (he also did both versions of the Emperor\'s Champion, the current Biovore model, and the current Fire Dragons aspect warriors). While I think that Juan\'s work is satisfactory (now to mention about 100 times better than I could do), it really doesn\'t compare to the master that is Jes Goodwin, especially when it comes to Space Marines, the line that he has almost singlehandedly designed since their inception from Rogue Trader.
Jes\' models, along with John Balanche\'s art and Andy Chambers\' fiction (and to a lesser extent also Rick Priestley and Jervis Johnson) is what really defines the WH40k universe, and its a little sad to see one of the big three move on to a new venture (although I\'m sure it pays more... and the plastic kits have been improving dramatically).
Anyway... my two cents.
