If every android did stock, but companies made custom apps etc they I would say android would be a beautiful experience.
Sadly the likes Samsung absolutely rape the android software and make it a bad experience IMO.
I'm an android guy ( although I'm moving to an iphone 6 plus, my first iphone since the iphone 4) , I have had the htc desire, gs2, gs3, note 3, htc one, nexus 5, in the last few years since the iphone 4.
And by far the worst phones I have had have been Samsung, I had the htc one and it's probably my favourite phone ever, it was beautifully manufactured , the soft ware was beautiful and buttery smooth, however the note 3 looked a a beast on paper and on video, got it and 5 months later sold it, the chrome paint was pealing off, performance got bad and no update to kik Kat even though it had been out for almost 7 months.
And that last point is the reason why I will never go back to android unless google finally fixes that problem.
Updates take far too long to roll out, and even when Samsung etc do release it, because of their contracts with carriers, it is the carries responsibility/ decision to decide when they roll out the update. So it has to go through 2 or 3 loops to get one. Major update, unlike iOS were applies presses the button and then boom most of the world gets the update there and then.
Google needs to invent a way to sort out this major problem, and they have took measures in the past like reducing the hard ware needs of android etc but that hasn't fixed a thing.

You do know Samsung is the one that sells most android phones (about 65% of global android marketshare), right? They must have done something right with TW or they wouldn't have sold millions of them. OTH, how many Nexus phones were sold compared to Galaxy lines?
There marketing alone is probably in the billions, which is why Samsung sells the most, they advertise the crap out of there devices, in Australia there is not a day goes by I don't see an advert from Samsung advertising there latest and greatest, and adverts do work, so I'm not surprised they sell the most.
Lg, sony and htc have all made better software for the phones, better materials, some have better specs, but then probably spend 10 percent of the amount Samsung spends advertising.
