Can someone tell me what is so special about stock Android? Is this a blasphemous question to ask around here? I just don't understand what's so special about it when a lot of the interesting bit about the Android Experience are in the apps. Even the Google apps are not married to the latest OS. THey are separate. It's not as if the OEMs are going out of their way to make Android worse...
If you've ever bought a new Windows PC, you have a good analogy to understand what the appeal is. Power users and computer enthusiasts don't appreciate having OEMs and computer resellers installing crap on top of Windows. Especially when the software slows down the system and takes up space, or even more annoyingly are the free trial software programs that used to come with desktops that would require purchase or paid subscriptions to work.
Some manufacturers develop useful and lightweight programs that are good, but even then you would rather have the option to pick and choose what is installed, or rather not have the computer come with anything except for unadulterated Windows.
The same is true of Android smartphones, but it's even worse than what went on (or still goes on, just set up a laptop for someone and ASUS put way too many of their own programs in) on the desktop side. Manufacturers make it hard to remove all those programs, they eat up memory and battery life, and very often they are poorly and inconsistently designed. There are cases to be made for
some OEM installed apps or features, especially those tied closely to hardware; I wouldn't want to lose IR functionality (which turns the phone into the best universal remote I've had, even easier to use than the Harmony One I owned) on my One or the camera features like Zoes or Highlights.
The problem, though, is that these companies aren't selective, and it's better in a lot of cases to have the stock, vanilla, AOSP, original, or whatever else you want to call it, Google version of Android. It's better to err on the side of speed, clean and consistent design, and minimalism than to throw in 1,000 programs and a cluttered and old interface that slows down what should otherwise be a lag-free and fast phone (speaking of the S4).
I honestly don't mind HTC's implementation of Android on the One at all, but would I prefer stock Android? Yes, but only if I could keep the camera features, the IR features (whether or not it's tied to HTC's TV program - so long as I can control my A/V setup, I'm good), and maybe most importantly still use Media Link HD, which came free with my phone and is an awesome way to wirelessly mirror my phone on my television and stream content from my phone to it. I love using my phone as a media streamer, it means I can use it as my primary media device almost anywhere.
Sense 5 otherwise doesn't bother me and it doesn't seem slow at all, and Blinkfeed I actually use quite often whenever I'm waiting in line or otherwise have some time to kill to look at headlines and read news, so really the only appealing thing about the Google edition for me would be that it doesn't come with the AT&T, Facebook, Twitter, etc. apps. I currently have all those apps in two folders which I never open. HTC otherwise doesn't have many gimmicky apps or features installed. Stock Android does look better overall, though, and if I were given the option of all the HTC features (via drivers preinstalled, and with the apps available to download through Play), but with stock Android underneath, I would take it.
