I don't think such a 'ranking' exists. This is possibly due to the fairly frequent 'Badge Engineering', where a particular kit might be re-boxed under a different company's name, for example, former Hasegawa Bf109K under the Revell lable.
Also, even in a particular manufacturer's product line, there can be variations in quality, fit, accuracy etc. Some might produce what, in general terms, is a good, nicely detailed kit, but might have a reputation, overall, for fit problems, accuracy, or inflated retail price. It's probably easier, and better, to search out individual kt reviews for a particular subject/scale.
