It is a matter of matching the characteristics of the seed to your application. In my case, there is no substantial deer preference between different cereal grains. I choose WR over the others because of the soil benefits and low fertility requirements. I've also done away with traditional tillage and got to no-till and T&M for my plots. WR has better germination rates when surface broadcast on my soil than oats and WW. I see no difference between branded and VNS WR. With daikon radish, I see zero difference, so I go with the least expensive, which is usually Groundhog radish. I find the same with turnips.
It has been a while since I've used chicory, but there is a difference there. Some chicories have lower tannin content than others which makes them more palatable to deer. I also find differences in clovers. My go-to clover has been Durana. It is an improved clover that I can by outside a mix. (Some BOB companies only sell their improved clover as part of mix with inexpensive annual clover like Berseem making the cost per pound of the improved seed astronomical). The characteristics that fit my application are drought resistance and persistence. It is slow to establish, but if you follow best practices of planting it in the fall with a WR nurse crop, and mow the WR in the first spring back to 6-8 inches each time it gets much taller than a foot, it establishes well.
In general, I find the coatings to be a negative. They generally decrease the number of seeds per pound. If the field has previously been planted with a legume that uses the same inoculant, there is usually enough in the soil (especially with no-till and min-till operations) that pre-inoculated seed is not necessary. It is cheaper to inoculate yourself if it is necessary.
