To get the Z5 or not??

So what do people think? I can upgrade my phone next week, currently on a nexus 5. Is the Z5 actually worth getting? (seems to be a lot of negative feedback about) or I'm thinking maybe the Nexus 5X (but the Z5 outspecs it in every way.... BUT... It's a nexus, it will be stupidly fast at all times)

Or what else if anything currently?
