I think it matters whether when you say under 200 feet, you mean usually in less than 100 feet or usually between 100 and 200. It also matters what species you are targeting.
Especially if you are typically over 100 feet, a B175H night be a better choice since the narrower beam will provide a lot more detail and target separation than a B175HW. If you will only have one transducer, the B175HW as noted will be more useful for midwater pelagic fish and shallow water bottom fishing than a B175H. I have a DFF-3D and a B175L so I really appreciate the greater detail of the B175H and can use the others for a wider view.
