All the posts that say more or less "some people just don't like change" are really missing the point.
A rather large number of posters have pointed out specific features that have indeed gone missing; have pointed out new features that are utterly worthless and a waste of space; have pointed out new features that are not merely buggy, but ill-conceived and poorly planned.
Yes, some posters have overlooked features, or not given new ones a fair chance. But a far larger number of posters have made very valid points, and nobody appears to be listening.
To name one, I think it is entirely valid to mention that the scrolling list of recent caches, found in far-off countries, is not relevant for most users; and many users are simply saying that they personally don't find it useful.
Missing features include the list stating the names, and total number of caches shown on the google maps for PQs. I and many other users found that very useful, and far quicker than using the map to navigate to one cache after another, and then using multiple clicks to open the individual caches. Other complaints mentioned by a large number of posters: the poor visual aspect of the beta maps; the large expanses of blank space on many pages, and the format changes that have destroyed the appearance of a great many cache listings.
Those are just a few examples; and they are being discussed in other threads in more detail; but it is apparent that a great many users have thought about these changes, have honestly tried out the new features, and are not happy.
