Flame toys win in term of design and engineering. I have Op and the KO tarn from MC. If you compare the price, Moshow win. But compare with the KO tarn from MC, they are both at the same price tag and I would say the KO tarn is the best of all three The problem with most of 3rd party metal build style figure is they are either too big for my taste or too simple in design. I still think bandai MB is the best overall. Sentinel/flame toy are cool too but they are so pricy. Bandai MB is on the higher price tag too, but I can still sell them later for the same or even higher than what I paid for them.
