Hi Michael,
I don’t use any phone for more than 6 month, so I’m not sure how durable it is. However, I have seen some build issues with the HTC One and probably you won’t like it. You can check out my HTC One review for more details. One more thing, if you have any issue with the HTC One, it will be very difficult and expensive to replace components.
Yes, I agree with most of your points.
I prefer the aluminum body of HTC One, it is just so gorgeous and different. I think HTC One has advantages in the design and awesome camera. However, the Galaxy S4 is still slightly better.
