My personal opinion is that Android is a hot mess. Things that I believe contribute to this opinion are:
1. Fragmentation. That has been beaten to death so no need to elaborate.
2. Manufacturer skins and one off customizations. Buy a new Android phone (non-Nexus version) and you will have 2-3 calendar, mail, and messaging apps installed day one walking out the store. The ones made by the manufacturer are using old open source code. I think this alone qualifies as a hot mess for user experience no matter how you dress it up.
3. Optimization and battery life. Android has a lot of bells and whistles that eat up your charge if left on. Dynamic wallpaper is one such example. Most folks leave off features they like because they want their battery life to last longer. Why have it if you can't really use it or need to charge your phone every few hours?
On the optimization side, I know folks in my small real world circle who have android phones (budget and high end) where the performance goes to crap after months of use. This always leads to a reset to get it humming along again. It truly reminds me of Windows all over again. While Apple has it's share of horror stories, I have various Apple devices in my family with iOS 5 and the classic iPod that perform the same as they did day 1. No reset, no nothing. I see this more times than not.
Anyways, this is my opinion and how I feel. I'm sure you have an Android phone and it probably runs fantastic. I think the examples I provided, most Android users would agree with and probably have experienced or seen those issues at some point or another. I'm sure the answer will be ROOT and uninstall this, that or another. Again, I would ask what kind of user experience is that? Who wants to troubleshoot and rom flash an essential device as your phone constantly?
