I like the Metzeler ME880's. Have them on the 900LT and they perform quite well. When I had my '10 Nomad, I replaced the stockers with the the Excedra Max's and they seemed like a good tire, too. However, I sold the bike before there was any appreciable wear on them. When I had my GL1800 Gold Wing, I used Dunlop Elite 3's front and rear. They were a decent tire, but both front and rear tires tended to cup early on and at about 2500 miles they started to get noisy, especially when the bike was leaned over in a curve. Seemed to handle OK, but the Metzelers on the Wing really transformed its handling.
