I've owned 5 Sigma lenses, still have 3 and never had an issue. Two of my Canon lenses have need fixing for decentering.
We can use statistics anyway we like when our sample sizes are so low.
I have owned three sigma lenses (120-300 OS, 85 1.4 and 105 OS macro) and all three are very well built (better than some canon lenses in fact), focus perfectly and are very, very sharp.
I also owned a tamron 28-75. Slow focusing and average build quality, but very good optically. Never gave me a problem.
On the other hand, I've had several problems with canon lenses, including L's.
And including a big white (300 2.8IS, bought brand new, was soft and had low contrast).
I've noticed that when many people have problems with a canon lens, specially an L, they downplay it.
When it's a third party lens, they complain and complain and complain.
Many are much more forgiving towards canon gear, which is, IMHO, unfair.
This reminds me of when I used to attend to (and photograph) local amateur moto X races.
Living on a small island, I quickly noticed most people were very biased towards japanese motorcycles.
When there was an engine failure with an european brand, people immediately criticized it for not being reliable.
When it was a japanese brand, it was just, well, bad luck...
Once there were even three engine failures on the same day from the same japanese manufacturer, and no one pointed out reliability as the factor. Some talked about very bad luck, others about a big coincidence and some claimed the local dealer's fault.
Not once was the reputation of the manufacturer at stake...
Top of the line sigma lenses are very good, IMHO.
Their lower line (cheaper lenses) leaves a lot to be desired (particularly older ones), have bad build quality and are indeed prone do mechanical failure, but then again, one has to consider the price sigma asks for them, since in some cases, you can find filters which actually cost more.
