I disagree. Hardware comes from the same manufacturers (Sony, Samsung etc). Its the software what makes a difference. Its why the original iPhone, 5 years ago, is more fluid that the Galaxy series.
I partially agree with you. To some, having bleeding-edge hardware is more important that a fluid OS. Having just left my iPhone 5 for a Sony (and first time Android user), I'll be the first to say iOS is put together better. More fluid, exactly. BUT, for me, I needed better hardware ( bigger screen) and being a tech person, I appreciate the better hardware that the Android market offers.
A few weeks into this, and getting more familiar with Android, I am able to make my Android phone more usable and enjoyable than what I had with my iPhone 5.
So, your statement above might be true for you, and some others, but it's by no means a blanket fact that covers everyone.
