Motorola has officially unveiled the new Moto G6, successor to the Moto G5S, and the latest entry in its popular budget G series. The Moto G line has recently been in the habit of bringing some premium smartphone features into the budget smartphone market, and the Moto G6 is no exception.

However, the mid-range Moto X4 from 2017 has its fair share of premium aspects, and it's within a reasonable distance price-wise to give the Moto G6 some competition. Both phones have incredibly diverse mobile carrier support as well, so they can ostensibly be reaching for the same potential customers.
