This one has been with me for a little while. There were a number of features present to "try out," as we do, and I picked the "pretty" version when it was on sale.
First thing I did was flip the clip. I don't know how much of a difference that made, but it has not slipped out of my pocket.
This knife taught me that I don't need assisted opening. Yet.
I also became sure that the blade shape is not my favorite.
However, I do appreciate the smooth scales. It's one of the few in my regular rotation that I can pull without it trying to bring my pocket with it.
It sounds like you would be happiest with a direct replacement.
That said, I do not believe there are any better folders in Magnacut for the money than the Belair. I highly recommend it.
The action is so smooth, I bet you won't miss the assistance. Blade is slightly thinner stock than a Leek, but I find the taller profile much easier for control. The clip point is personally my favorite. Very slim, very light in the pocket, very comfy in my hands. Better grip surface if the smooth steel is your only dislike.
I'd say get your Leek, but if budget allows try both.
