The only bad thing that I can say about them is that they run Android, but it's not easy to escape that.

I don't realy get what you mean, I mean all of them run android as a stock OS init?

I mean that Android is a terrible OS.
It's main language is Java, which is the worst decision that they could have made. On top of that, it uses a heavily modified, but outdated Linux kernel. Linux is fine for a kernel, but they aren't up to date with it.

I've had a Moto Z phone for a couple years. I'd highly recommend them.

I second this.

A handful of work friends have the Moto Z, most of which are heavy users and I've only heard positive feedback thus far.

It's over, my next phone for playing around with android will be OP5T, but thank you for the suggestions!
