The clear choice to me is the Gravelking.
I've ridden both the Pasela and Gravelking in various sizes and the Gravelking is the clear winner. The sidewalls are slightly more supple, the tread more appropriate for paved riding (despite the name), and the weight is slightly less. As far as I can tell they both offer really good puncture protection. The ride feel of the Gravelking has been noticeably better for me.
I would guess many on the C&V forum haven't tried the GK yet because it is a newer product. But definitely worth it.
