I have both version of the Pasela. I honestly can’t say that I would notice a huge difference between them. I’ve always figured that the differences between my bikes were more significant than the tires. I usually trend towards the flat resistant tires because I often find glass along my ride.

Once upon a time I shelled out the money for high zoot challenge tires. I got so many flats that year that it didn’t feel worth it.

Either version of the pasela is a good tire. I’d say make the choice depending on what sort of roads and debris you will ride on.

I bought the Swift sand canyons based on feedback I read here. I like them a lot too, but again, I don’t know if I’m sensitive enough to the nuances of tires like others. I couldn’t say if I notice a difference compared to paselas.
