Tamron 18-200 Vs Canon 18-135

I have a Tamron 18-200 for a general carry-around lens when traveling. I bought it when to use with a digital Rebel. I now have a 60D and would like improved image quality. I'm looking for opinions on how much improvement I could expect by switching to a Canon EF-S 18-135mm f/3.5-5.6 IS STM Lens. I know I lose some range but I don't use the longer settings all that often. I have a Canon 70-300 USM that I use for wildlife and am happy with the results.

Heya,
The IQ improvements from optics from the 18-135 STM over the Tamron 18-200 are going to be minor. Sure, it's an improvement, but it's not worth the cost if you are ok with a very minor improvement. If you want to see a big difference, you'll need something substantially sharper, or faster, or both. Depending on your focal length needs, this is where you start looking at a 70-200 flavor of some kind. Or even a prime. If you're looking for something to include the wide angle and the telephoto, you're already on a lens that is fine for that. Getting a newer version of a super tele zoom (18-2xx) for APS-C, is always going to be a bit softer than options that do not include the wide angle side (like a 70-200).
If you want an improvement and you want to keep as much as possible on the wide end, without the very wide end, consider a 55-250 STM instead.
Also, how you shoot and what settings you use come into play.
What aperture are you typically shooting at? I ask because if you're shooting that zoom wide open, it will sharpen up if you stop down.
Very best,

The D90 was the only camera used to compare the Nikon 18-200 and the Tamron 18-270 for these webpage photos. UPDATE JANUARY 14, 2013. It's hard to believe that it's been 4 years since I commented on the Tamron and Nikon super zooms. Lots of changes in 4 years: D80 gone, D90 gone, 16-85 gone, 18-200 gone. No question the USM can be faster but the 18-200 Canon is a micro motor so I don't think it will be much quieter. The Tamron does hunt with the slow aperture above 200mm, that is more a artifact that the auto focus of most cameras struggle when aperture gets much above 5.6.
