"I already know the friend who will come to me tomorrow that his HTC has and 8 core processor while Apple has only six. The point is: it is all useless without the whole package being perfect."
Android, just like iOS or any other OS, requires non-crap hardware (not amazing, just well designed) and an OEM that doesn't bloat it up with tons of crap. Newer versions of iOS run like crap on older iPhones, because the OS is designed for newer hardware. Android runs beautifully on well designed hardware, even inexpensive hardware like the Moto G. It runs great without bloated skins and shovelware that "adds value".
It baffles me that Google are so bad at this.
