My 2 cents:

brought Valuable point about both knives in question might have issues with cleaning.
I would not disagree that frame lock will be easier to clean. However, and this is only my opinion, if I have to prioritize,
I’d put the metal frame and cleaning last in my list, after useful blade geometry, non slippery grip and type of locking mechanism.
Having used Griptilian for years, also the Rat, in very dusty environment, out in the field, both knives covered with dirt and grime, I am positive that the Grip will have almost no issue with functioning even if the studs opening have some stuff in it. Same goes for the Rat too, the lock is protected some how between the scales and if just rinsed, almost all stuff will be flushed away, there is nothing to hold it there.
With this said, from both knives, the omega springs are the more vulnerable element in the Grip and IMO

have a point here, not picking the Grip is just preventative measure, why dealing with two small spring that could rust if you can pick the Rat.
