The real question is "what is your goal"?
Winter wheat "might" be more preferred in some areas over winter rye, in certain seasons.
BUT.........
What benefits do each species have over the other outside of simple preference levels?
Winter Rye beats winter wheat (outside of preference, which is debatable and site specific) on basically every other benefit a crop can have.
Winter rye is
-Allelopathic, suppressing undesirable weed seeds.
-Easily germinated, improving growth on sub par soil.
-Fast growing, providing a protective "sacrificial" crop for secondary species planted in the same stand.
-Organic matter producer, improving future germination rate, moisture retention, and nutrient holding capacity by quickly increasing the OM.
-Double season, providing early/mid fall food and becoming palatable in the spring before even clover.
Winter wheat might reasonably be able to be mentioned for two of these benefits, both of which are performed better by winter rye... those are "fast growing/nurse crop" and "OM producer". Once again... Rye outperforms winter wheat in both of winter wheats best attributes.
Winter wheat is left ONLY being able to claim that it MAY be more attractive to deer in some locations, in some seasons......
Unless your soils don't need building in any way..... Winter Rye wins.
