I would go with the Tamron 16-300mm, 18-400mm or Sigma 18-300mm over the Canon 18-200mm. Canon's 18-135mm is pretty good if 135mm is long enough for you.
Tamron 16-300mm has the advantage of being wider, which is helpful for Canon 1.6x crop factor, but the Sigma 18-300mm is sharper at 300mm. 18-400mm is still relatively new, but I assume it would be sharper at 300mm since these all-in-one lenses tend to be soft at the long end.
