When my D7000 was my primary body, I had the 18-200 and used it quite frequently (second only to 17-55 2.8) when I wanted to be ready for just about anything (except low light). While many folks look down on this lens, I liked it and got many nice shots. While it might not be quite as sharp as the 24-120, it gives you more range on both ends. Can't comment on the 24-120 since I haven't owned one.
