Which bike should I get? Kawasaki Z800 or Yamaha MT-09?

Hi guys, I am thinking to get a new bike. At the moment I’ve got a Yamaha X Max 250 ABS 2016. I want to get a bigger one, something like Kawasaki Z800 or Yamaha MT-09.
Which one should I get?
Should I trust in a Kawasaki engine? Are they long lasting? Or should I bet for Yamaha? In this case a Yamaha MT-09.
I know the 2 of them are good enough but any advises before I get it?
