I think it's not correct to compare icons that were designed for two completely different style of looks. For example, the old compass icon is perfectly fine for "old" iOS 6 look, but would look awful in iOS 7, however the new icon looks good in iOS 7, but would be absolutely inappropriate for iOS 6.
The better question would be simply to show only new icons and for each ask do you like it, yes/no? It also is more important question, because icon can be horrible, but still an improvement over previous version.
Also, IMHO icons lack some of attention to details and while generally may be perceived as good, they have some "hidden" flaws that aren't usually present in Apple's designs which usually stand even most nitpicky examination. For example, the Music icon looks fine and the poll result shows that people don't see any problems with it, however for people who are familiar with musical notation, the line with rounded corners that groups two notes is just weird, because in real notation these group lines are never rounded. Why did they round corners on that icon? Even if it doesn't effect user impression of the icon, it also doesn't make any sense, which is not typical of Apple designs where every tiny detail has been thought through.
