You should have noted, while typing that list, that there are virtually no complaints about the screen, except for what appears to be manufacturing defects (uniformity issues). Which should tell you all you want to know, i.e. that people don't complain just for the sake of it.
Faster CPU/GPU? CPU, not so much. GPU, debatable, since for example the 15" got a better dGPU but a much weaker iGPU. Better build quality? Not even sure how to measure that, but based on the number of failures experienced by people on this forum, probably not. Better keyboard? I strongly disagree. That's your opinion, not even the majority opinion.
Ports? For a lot of people, me included, the new ports absolutely suck. MagSafe? That's a regression for sure.
So the question is not whether this new MBP line is plausibly better at everything compared to the previous. It clearly isn't, and even to suggest such a far-fetched thing insults our intelligence. The question is whether the compromises and questionable choices made by Apple with this laptop line can be overlooked and lived with. And this answer is purely subjective and depends on individual needs.
Don't be daft. Only if your comparison group includes exclusively laptops running OSX. But that's a meaningless standard for anybody except die-hard Apple fans.
Of course I can find a better 13" laptop, and you can too. Go and configure a 13" HP Envy, you'll get a way better deal and not for the same money, for hundreds less. And while you come to this thread to dismiss forum criticism about the MBP, you use it to explain why HP and Dell make terrible machines.
