I'd say go for the Keyence and not just because I own one either. I have yet to hear any complaints or malfunctions with the Keyence Zero V Extreme! Not to say that there aren't any or that it won't happen, but I have already heard tons of stories of people turning their LRP Quantum Comps into Marshmellow toasters, lol. Although I realize that there are far more of the Quantums out there than the Extreme's which increases the amount of failures, but never the less. Actually I have never heard any complaints about any Keyence esc, even their older models! That in and of itself is a good sign!
