Any Problems Mixing Hikvision H.264+ And H.265+ Cameras?

I am quite new using H.265 NVR's and Cameras. I am planning a system with a HIKVISION H.265+ compatible NVR, Two H.265+ compatible cameras and four H.264+ compatible cameras. Is there any compelling reason I should not mix the cameras? Is there a significant benefit to keeping all the cameras H.265+ compatible? Products I am planning to use: HIKVISION DS-7608NI-12/8P, TWO DS-2CD2185FWD-I, FOUR DS-2CD2142FWD-I.
