When just looking at Sigma lenses, have you experienced more decentering in zooms over primes or vice versa? And what about other brands?

If I had to come up with a ranking (best to worst):
1. Olympus FT
2. Nikon
3. Canon
4. Olympus MFT
5. Sony
6. Panasonic
7. Tamron
8. Pentax
9. Sigma
10. Samsung
11. Tokina
This needs to be correlated to the service quality - locally it's roughly:
1. Olympus
2. Nikon
3. Pentax
4. Canon
5. Sigma
6. Tamron
7. Panasonic
8. Sony
9. Tokina
10. Samsung
Prime lenses are, of course, better centered than zooms. We've rarely seen issues with primes actually.
The biggest problem makers are ultra-wide zoom lenses (usually issues at the image sides) and high ratio zoom lenses (center centering -> contrast).

From your reviews, stabilized lenses seem to have more problems

Yes, higher complexity is never a road without impacts.
No wonder it is written in lens name
