So don't use TW then.....Use a different launcher like Nova. Problem solved.....don't need those features...disable them so they are not using any resources on the phone. problem solved....now can you do that on an iPhone? can you use a different launcher if you choose to do so? What if you want different features than the current iPhone launcher has? Can you just install another one? See how that works in reverse too? Don't like TW....don't use it...install another one......don't like the one on the iphone? You stuck...Apple decided they know what is best for you so you are stuck with what they chose for you......
Don't like the features or options on an Android phone? Disable them in system settings. problem solved......Can you do that in IOS?
So I had the note 2. I downloaded Nova launcher on the phone. Still could had menus that I thought were ugly. It can change the way your home screens and app drawer look, but it still can change the look of the whole OS. I understand what you are trying to say, and I am glad you find that downloading a new launcher helps you. When I buy a phone I want to phone I like right out of the box. The iPhone does that for me. My Nexus 5 and stock android does that.
Enjoy your Samsung, but trying to defend your purchase by bashing the completion is getting old. Both sides do it, but really if this is all this is coming down to then this will never end.
