This was my first FireForge plastic kit and sadly I wasa bit disappointed.
The plastic is on the softer side, the details aren't crisp, and the mold lines were annoying. The pieces also were hard to line up (neck holes were shallow, it was hard to center the torso on the legs, the arms were difficult to fit against the torso, the separate leg on the kneeling pose was a nightmare).
That being said, if you can struggle through assembly & clean-up, they look pretty good painted and again, the price per sprue is reasonable. I can't think of anyone else making multi-piece plastic Sohei and you do get an interesting assortment of bits on the sprue.
