As outsiders it's very difficult to tell which aspects of the overall product are due to design differences and which are due to different manufacturing technologies. It's possible both design and manufacturing are better (for AMD/TSMC), but the only one that is obviously true is that the manufacturing is better. We simply would not have a conclusive answer about who has the better designs unless they used the same fab, giving them the same possible feature set. And if they did, I suspect AMD would have a huge advantage from their existing relationship working with TSMC.

AMD's designs are good because Zen+ was better than Zen, and Zen 2 is better than Zen+. Some of the gains may be from die shrink, but if die shrinking was all you needed to do, TSMC would license a z80, drop it on their latest process and call it a day.
