Your brand tier classification is a big mistake. One should never classify any GPU AIB like this ; base on AIB brand alone.
Example , in my opinion , i will deem lower tier Zotac cards with the same GPU the same as your Manli and OCPC ones base on build quality.
I mostly look at the PCB and see what capacitors they use, power stages/discrete mosfets. Always compare to the FE models or reference models from Nvidia. That is the baseline. If AIB version uses inferior or less components than FE/reference , they are low tier.
Sometimes AIB like Gigabyte share the same PCB between two different model range ; Eagle and Gaming OC, but the amount of components populated on the PCB is different..
Another example is Galax , they look like lower tier AIB but their Hall of Fame series cards are excellent. Same with Colorful with their Vulcan OC series cards.

I cannot confirm Asus TUF uses Japanese capacitors though. At least I know the RTX 3080 TUF does not. It has a lot of Apaq capacitors, they are from Taiwan . The Strix version however uses Panasonic capacitors, of course, there is a big difference in price though

See the round logo on the capacitor, that is Apaq company logo.
