Retrofitting Analog System - Considering AHD And CVI

I need input (hopefully my timings good) on retrofit for a large Analog system with 28 cameras. Currently 2- 16ch Digital WatchDog V-max recorders which are horrific along with cameras, first generation recorders tech support mentioned today. Client doesn't want to upgrade to network IP and pay for cabling job. Or I could do coaxial conversion with Vigitron as example, which adds cost, I looked at article interpretation.

I have read articles on here pertaining to my situation CVI and AHD "tested" however real life installations, performance, best quality is more desirable. Of which Manufacture is going to be best for longevity by your evaluation, in which possibly this particular technology stays around?
