I have a very small bias against the so-called 'Turkish' or 'California' clip, simply due to their narrower spine-to-edge width (in some, not all examples). I tend to favor the (usually) broader regular clip blades, as I believe that allows for a more gradual, thinning taper in cross-section, towards the edge. A narrower blade, from spine-to-edge, needs a quicker taper to the edge from the spine, to keep some thinness behind the edge. The few Turkish/California clip examples I have, like a Camillus muskrat pattern, are all pretty narrow and a bit thicker behind the edge than I'd ideally prefer. That's my priority in almost all the knives I use & carry - I REALLY favor the thinner grinds overall. And for clip blades in general, I also place emphasis on making the tips as pointy as possible. I like them for reaching into tight spots to stab and retrieve things, like picking out fruits from cactus, for example.
But again, I also realize not all Turkish clip grinds are the same, and some can be thinner than others if they're well-executed in advance. Same can be said for the 'regular' clips. Some are better and thinner than others. My slight bias is just that - it's not that I'd pass one up based only on the blade's overall profile, if I could see for myself it's as thin as I want it to be.
I don't think I'd feel a need to deliberately carry two different clip blades, unless they just happen to be incidental in the knives I choose to carry for other purposes everyday. And today, in fact, I am carrying a Buck 301, with its nice, pointy clip, and a lightweight Buck 110, with its clip.
