To back up a bit, what is the point of the question? Are you a Nikon or a Canon shooter? Are there specific lenses that you want/need for one brand or there other?
To back up even further, once you have determined that you need a particular lens with functional characteristics X, Y, and Z, "lens test" results may (or may not!) be useful in parsing out very small differences between otherwise identical options. However... in most cases they are almost completely irrelevant.
Let's say that you want a lens to cover (to make up numbers) the 20-75mm range at f/3 on your Nikocantaxony camera. You look at the "lens test" results and find out that Pensoncanikon makes the "best" 20-75mm f/3 lens which scores 73 on the DeadOX scale. You don't know what that means, but it is The Biggest Number so it must be best.
What do you do?
1. Sell your Nikocantaxony gear and replace it with a Pensoncanikon system so that you can have a lens that scores 73 instead of 72.
2. Find some third-party adapter than lets you put the Pensoncanikon lens on your Nikocantaxony camera, even though you'll have to give up AF and automatic aperture control and can't use filters.
3. Continue to use your Nikocantoxony setup and buy its deficient 72-rated lens and go on a forum and complain about how Nikocantoxony is "falling behind" Pensoncanikon.
4. Instead of getting the deficient Nikocantoxony 20-75mm f/3 lens that rates 72 instead of 73 buy the numerically superior Nikocantoxony 300mm f/1.4 SuperGonzoLator lens that rates 74 by comparison to Pensoncanikon's 300mm f/1.4 PentaMachoNon X III that only rates 71. You don't need and cannot afford this lens but, hey, it scores higher!
And what do those rating numbers actually mean?
