The Hot Toys quarter scale is really nice but not perfect. The overall construction is more accurate with all the armor pieces being the right proportions (compared to the Sideshow 1/4 scale with its funky gauntlets). But the paint app, while beautiful and super detailed, isn't really accurate. In fact, SuperJedi did an awesome repaint of it and posted it on Facebook. He used a more accurate color scheme and replicated the correct damage on the armor.
Also, for those who pay attention to the subtle details, it still has the wrong chest symbol like virtually every other Boba Fett. And I find the blaster is REALLY big, too. The only other criticism of the figure I have is that for a "figure", its range of motion is pretty limited. I can't get it to pose like the publicity shots. Mine is just standing on the base with the blaster at its side.
But don't get me wrong: it's gorgeous and I love it and of the three 1/4 scale Fett's that have been released, it is by far the most accurate.
