Well, I think this one is fairly obvious. Pentax is basically the only manufacturer offering APS-C pancakes. If you want to stay small with primes there's no way around Pentax. The Pentax 60-250 is also unique. There're more. THis is basically the advantage of a dedicated APS-C lineup and not some sort of mix.

I agree on the APS-C pancakes. Not that they are APS-C (it will not make much of a difference if they are FF, not in size, not in weight), but that they are pancakes.
Of course, for Nikon and Canon there are the Voigtlander 20 and 40mm pancakes, but they lack the AF the Pentax lenses offer.
About the uniqueness of the Pentax 60-250mm f4 lens... It is not as unique as one might like.
Is it unique in its focal lengths? Not exactly, there are the Canon 55-250mm and Nikon 55-300mm APS-C lenses. Those are f4-5.6 lenses, yes. And in the long end they don't quite reach the same performance.
But they are way cheaper and lighter.
But, with weather sealing and build quality, it sort of looks unique. However, the Canon EF 70-200mm f4 L IS USM lens comes remarkably close in concept... but it is a full frame lens.
On APS-C the Canon reaches a 320mm equivalent, where the Pentax reaches 375mm. That is at infinity. But how is that at MFD?
There the Canon has the longer focal length.
Where the Pentax reaches 1:6.7 at 1.1 meters (MFD), the Canon reaches 1:4.8 at 1.2 meters (MFD).
So it is a draw. Where at infinity the Pentax probably has a small edge in tele reach, the Canon makes up for it at closer than infinity ranges.
Weight? The Pentax weighs1040g, the Canon weighs 760g.
Size? Pentax: 82x168mm. Canon: 76x172mm. And the Pentax extends a lot while zooming.
IQ? Both are very good.
Price? I think the Canon actually costs a bit less.
So all in all, I do not see the uniqueness of the Pentax 60-250mm f4. It being APS-C only does not bring advantages (it still is bigger and heavier), and its focal range is totally comparable to that of the Canon 70-200mm f4 L IS USM.
Or maybe one could call both the Canon and the Pentax unique, compared to the other brands.
