I've never owned any Hot Toys figures. They're hard to come by in Australia. NECA stuff, on the other hand is easy. What's more, the NECA stuff is substantially cheaper as it's sold in huge volume. NECA have some great stuff - it's not perfect but for the price point it's more than acceptable.
I've had a couple of figures that had some QA issues. Not many out of the ones I've bought. I remind myself these are essentially glorified toys at a decent price point and the quality is generally pretty good.
More NECA stuff is welcome in my life. I do like it. I understand some people want perfection but really, for the amount of detail, articulation and generally good quality on offer, NECA got it all wrapped up for around US$25. Not bad; and aimed at a mass market helps to keep the price reasonable.
