The challenge with Reolink is their app/update support. After a couple of years they effectively abandon users of a certain app and updates are no longer forthcoming for cameras and NVRs. That’s generally not the case with Hikvision where they expect a camera install to be good for years and support the equipment accordingly. Reolink is consumer kit (like Swann etc) and they basically expect you buy new kit on a regular basis if you want current support.
Other than that I doubt you’d see much difference between Reolink and your Hikvision system in terms of performance.
