Familiarity: I've put it through the wringer
After 1000s of miles I've got to say this is one of my favorite tires of all time. They're not the lightest or most supple or fastest rolling but unlike some fancier tires they've got really good durability while still rolling nicely.
On gravel tires you always have to consider how much time you'll actually be on gravel versus pavement and this is one of those that works equally well on both. I commute daily on these and the ride is very comfortable, maybe not as fast as other tires but then I hop onto a dirt track and the tires roll just as nicely. They're not a mountain tire but all things considered the only time I really find them lacking off road is when they lose traction on cheap climbs. But I've bombed through sharp lava rock gardens on jeep trails and they've shrugged all that off.
And for icing on the cake, tan wall tires always look good on gravel bikes!
