The 93 mm version C3 SS is better built (mine was from Lightake), the 98 mm (DX) is not as nice. N-Light B2S is pretty much sold out everywhere. But if you are into neutral tints the N-Light B1 might be worth a consideration, but it's twice the price tag of the C3 though. You get neutral tint, high PWM ,metal tailcap, no-strobes and hopefully a suiting diffuser in return.
