Ok, well that's a pretty broad statement. There are lenses made by both of those companies that far exceed anything Canon makes in a reasonable equivalent. Granted most of Canon's L lineup is far superior to a lot of third-party lenses, but to group all third-party lenses as crap is wrong. In addition, you're saying all manual focus lenses such as Leicas, Zeiss, Voigtlander and others suck just because they're not made by Canon. Many of these lenses have much better IQ than Canon's but don't have auto-focus.
Also, have you tried any of Sigma, Tokina or others' better lens offerings or just their lower end options? For instance, Sigma's new 50mm f/1.4 is considered by many to be superior to Canon's version. They're also releasing a few highly anticipated lenses such as an 85mm f/1.4 that could potentially be a better option than either of Canon's because of the 85L's slow focusing and the 85 f/1.8's tendency towards chromatic aberration and fringing at times. I'll say for the most part you get what you pay for, whether you buy Sigma, Canon or any other number of brands. I can provide more specific lens examples, but the important thing is to do research on each lens.
