Depends on what you use the scope for.
For FT you want a big mag with a big front end with a narrow depth of field for rangefinding. Mil dots are not really relevant as these scopes would be dialled in.
Hunting/hft is better suited to a fixed mag with a big depth of field as you don't have time to rangefind and dial in. Thats when the mil dots come in.
Horses for courses.
