I only notice the jimping when it gives me the ouchies when I'm bearing down on the knife cutting thick cardboard, treelimbs in the garden and so forth. Hard use as it's popularly called. I feel like jimping there causes more problems than it solves.
For stopping my hand moving forward on the handle the choil on the handle and the hump on the blade stops the hand, for stopping the hand moving of the back of the handle I find the shape of the handle to be more important. And let's not forget the FRN texture on the sides which I would argue is way more important than the jimping on the top in regards to "grippytude". The vaseline-factory is perilous!
I've given serious thought to filling the ridges up with epoxy or ca glue to smoothen it out.
My vote is for an Endela 2 without the jimping on the top of the handle and Rock Jumper-esque rounded of underside of the handle such as in the last picture.

Bonus image. This is my old suggestion of a smoothed out Endela handle which would give a more universal fit for hands of all sizes.
