I've got those same Hankooks on my SE, and they've been great. I got about 14k miles out of the fronts before I had to replace them, but the rears are still going strong at 17k miles. And I'm not a saint on the road, so that's saying something.
I've found them to be great in all weather conditions. They're not the cheapest tires, but they're worth it.
As for all-season tires, I've had good experiences with Michelin Cross Climates, but I've never had them on a MINI.
Remember, regen braking means your tires will wear out faster than on an ICE car, but your brakes will last longer. And the stock Hankooks are awesome. I'll definitely replace them with the same tires when I need to.
