Haven’t used tubeless but used both PR and SB pro series tyres and the PR race vulcanised tyres.
Pro series tyres are utter arses to fit on tubeless compatible rims but lovely rolling and good compound. Grip predicable and good in both wet and dry. Both have double puncture strip in them (updated as originally PR only had single) which works fairly well, I ran SB all winter with 1 puncture which is pretty good for Devon lanes. On 21mm internal rims the PR came up about 30mm and the SB about 33mm.
Pro series uses a super poly casing rather than cotton (300 vs 260 tpi for PR vs SB). The white version uses a silk casing which might rot if it gets really wet and is left wet.

Tricky question but to a point how long they stay sharp and how comfy they are in your hand. Steel that’s been heat treated and worked more is more brittle (harder) and so can be sharpened to a finer angle without deforming. Softer steels cannot be sharpened to the same angle but are less prone to chipping.
Cheaper knives tend to be made of softer steels so when sharpened to a reasonable angle so that you chop things easily, the edge doesn’t last long. Knives of harder steels can maintain a finer cutting edge for longer but before they deform but take more effort to sharpen. Knives made of very hard steel stay sharp for ages at normal angles or can be made very very sharp. But the brittleness means they’re prone to chipping against hard surfaces.
