I have been using Sony Xperia ZR for the past 3 years now and I believe it is worthy of the payment you have paid for. Sony has been delivering lot amounts of desirable products for the past few decades and the company is to be trusted. Going into the specifications the phone has 2GB RAM, 8GB internal storage, Expandable memory upto 32GB, Rear Camera of 13MP and front camera is VGA . The phone comes with waterproof and dustproof guarantee with Ingress Protection(IP) [even One Plus 5 doesnt have]. The phone has some heating issues and lags very less.
