Not according to the reviewers. . . none of the Android phones or tablets can offer anything close to the iOS ecosystem, integration, or ease of use. As for cost? They cost about the same for flagship level handsets. Anything that is in the "next to nothing" on contract is older technology and definitely not competitive. NONE of them offer true 64 bit processors. . . and the Apple iPhone 6 is blowing the Android quad processor competition away on almost every bench mark with dual processors.
That's because Apple controls both the software and hardware side, so iOS and the Ax series of system on a chip (SoC) are extremely optimized for each other. I do think, though, that the next versions of iOS and MacOS X coming this fall will likely be mostly bug fixes and code optimization, similiar to the Snow Leopard release of MacOS X.
