Just to add my 2 cents, I'd say that in the field, both knives open and close "fast enough", I don't see any advantage in being able to get the blade opened half a second faster. For me this argument suits better the "urban" users who may think about using the knife for SD, pretty foolish with or without a real good training...
If we stick to what matters:
- toughness: both knives have it,
- materials, fit and finish quality: both are in the same range,
- lock strength and reliability: both knives have extremely good locks, although I would give the lockback a plus when it comes to high constraints,
- sharpness: out of the box, the spydies win anytime over the BMs, on top of that, I would say that the spydies always have better blade geometries anyway, better usage potential
- ergos: again the spydies have (and probably always will) the edge over the BMs
- price: on this comparison, the manix is the most affordable, no possible debate.
Overall, the manix is the winner here, no doubt, it's a much better EDC, with great potential for any incoming task to deal with, maybe the only role where I would see the Rukus preferred, is in a military one (longer blade and overall fitting colors...)
