Not true. Hardware doesn't compensate for software shortcomings.
Not true. I've used Android AND iOS since each platform was released in 2007 and 2008 respectively. I've owned every model of iPhone up to the current iP6+ I'm composing this post on.
During that same time frame I've owned over forty new Androids from Samsung, HTC, Motorola, Huawei, LG, OPPO, and others. In the first few years Rooting my Androids did serve a purpose. But since Ice Cream Sandwich version 4.0 rooting is no longer needed. Speed smooth and fluid operation is every bit as good as iOS.
Any good smartphone is designed by highly skilled engineers working within the parameters issued to them by their employer, these are large scale Enterprises like Apple that know what they're doing.
Both my Nexus 6 and iPhone 6 Plus are two very different yet excellent smartphones. I speak from long term personal experience, not some quote or review I've read by some biased writer.
