What do longtime iOS users who convert to Android think of Android?

Some context first: I've used iOS since the original iPod touch came out, and had an iPhone since the iPhone 4 came to Verizon. I now own a Verizon iPhone 5 and a Verizon iPad (fourth-generation) and plan to upgrade at the end of my cycle to the next iPhone. (Eighth-generation... or nineth, if you count the 5c in the same generational lineup) I got the original Nexus 7 when it was brand new; I sold it about a month later. The device itself was wonderful, that's how it passed my research for me to purchase it. The reason I couldn't stand it anymore was because it runs Android. I think Android works best at around 7" of screen space while iOS works best at 9.7" of screen space. 10" Android tablets seemed too big to me, like the screen real estate wasn't used effectively by native or downloaded apps. The design of Android devices also feels less professional and elegant than iOS devices, which started to bug me after awhile. It's also worth mentioning that I owned my original-generation iPad at the same time I had my Nexus 7. I found the Nexus 7 much better for gaming, especially Temple Run (don't judge me) and the iPad best for pretty much everything else. Being so old, my iPad was pretty slow... but I still preferred it. I just used the Nexus when I wanted to browse the web or get something done more quickly, but now that I have a newer iPad I don't ever have that problem anymore. I mentioned earlier that Android devices aren't as elegant as iOS devices; this isn't just hardware. Even worse is the software, which consists of UIs and icons that just felt off to me. They weren't necessarily bad, they just felt like they were missing something. I remember feeling like freeing applications from square icons was not necessarily good for mobile devices... both iOS and Windows Phone devices constrain icons to boxes, and consequently they both look better than Android icons. The UIs were entirely different: just like I don't really like iOS 7 UI design as much as I like iOS 6 UI design, I feel again like something was just off with Android UI design. It felt much too flat and the color schemes weren't too great. The most important part of a device in my opinion is how it actually performs, regardless of how it looks: one of the major reasons I still plan on upgrading my iOS devices when it comes time again, despite the eye-sore that is iOS 7. For me, Android ("Jelly Bean" at the time I had my tablet... how about those names, another thing I don't like about Android) did indeed work, just not as well as iOS does. It was more free and open, which I can see as being appealing to certain people, but it caused more problems than it fixed. How about Google Play? I've never used the Amazon Appstore, but from what I hear it pales in comparison to Google Play anyway. Google Play has some great apps, but it also has TONS of "crap apps" that litter the entire store. Sure, Android is now a fierce competitor with iOS for the most apps available for download... but that is undoubtedly because of all the complete junk applications available from Google Play. How many "sexy girls" wallpaper packs does one application download service need exactly? I would never leave a child of mine to roam Google Play unsupervised. That's just some of the points I can think of right now as to my opinion of Android. I underestimated just how glad I am that iOS exists! Experiencing Android first-hand made me realize that Windows Phone would be my platform if iOS didn't exist. (I actually like Windows Phone 8... Windows 8 in general. But that's an entirely different subject with its own list of flaws) Thinking about this, I can't help but wonder how wonderful the mobile experience could be if Apple, Microsoft, and Google worked together. They could make an amazing OS together. (Or just Apple and Microsoft...)
