I've run 2 pairs of Conti Trail Attack 2 and 3 pairs of Bridgestone Battlewings. I find grip and mileage to be the same, the only difference is the Conti's have a slower turn in, so the bike doesn't fall into corners as easily, but you soon get used to it, not a deal breaker. I use the BW more because they're cheaper. I get about 12K - 13K miles out of each, YRMV.
