I don't have the 18-135, but I do have the 17-70 and it's a good quality lens, though at 70mm, corners are a bit softer. From what I've heard, the 18-135 doesn't perform as well above 70mm. And at 70mm it's slower than the 17-70. I think it's already f/5.6 there, so the difference is a full stop. So if you are after maximum quality, I'd recommend the 17-70. Unfortunately, that has no WR though, and the autofocus seems slower too.

I would invite you to look at the comments left on both of these lenses in the lens Data Base.
