I've had both. If mythos was not painted by sideshow and made in 1/5 it might be close to this, but they fell down on the paint and even the repainted ones are still fail scale and nowhere near as detailed. I do like what they tried to accomplish with it, but the production piece just did nothing for me.
That's how I feel about the Mythos Vader. Paint was not the way I would like it and the scale. I wish it was 1/4 because I could at least commission someone to paint it. Alas, I passed on it and never looked back.
Going back to the IS Vader.
It has it's issues as well, poor design with the chest and belt lighting, paint on the details of his belt and chest light box, but these are things that I can either live with or correct later on down the line.
The moment I saw the proto for this I had that adrenaline rush. It's the feeling that made me preorder instantly which brings me to my last point... for anyone that has any doubts once you've seen it in-hand, do yourself a favor and return it.
You shouldn't have any borderline feelings in this hobby. First of all, this industry is too expensive. Second, there's other great alternatives or you can always wait for upcoming pieces. Lastly, don't hold on to something in your collection that gives you regrets. Sell it, return it, get rid of it and make someone else a happy collector.
