The Dialyt is a tough, durable spotter, but does not control CA as well as the other options on your list. This is likely due to the lack of ED glass in the 5 piece achromat objective assembly. Another issue with the Dialyt is the short and critical eye relief. When I tried one I found it so noticeable I went to the Zeiss website for the technical data, and the eye relief specs were suspiciously absent. If you are really looking towards Zeiss, the Diascope 65 is much better scope, and is often found lightly used around the price of the Dialyt. Furthermore, if you want to digiscope, the Diascope also has many accessories (proprietary and 3rd party) available, while the Dialyt does not.
IMO, the Razor 16-48X65 is the best choice, from your list, for your all-around uses, especially if high-contrast viewing is on your menu, where the Dialyt will struggle.
