Delta's skytrax rating?

Ik skytrax is a scam, enough said.

But like... i feel that at this point Delta being ranked 3 stars isnt doing it justice. Based off my experiences I think Delta should definitely be four stars. Most likely a low-end four star carrier, but it deserves its' fourth star. Its proven to be much better than even some European full-service carriers that have four stars, like BA.

Ur thoughts?
