The main difference between the playability of tight bent v tight fescue v even tight bluegrass would probably be their growth characteristics. The bents are stoloniferous, so the plant grows sideways as well as upright. Bluegrass is similar, though the rizomes that grow sideways are deeper down than with bent, so a shallower divot would be met with less resistance. The fine fescue is a bunch type grass, with little to no sideways growth, which would give little to know resistance to a divot being taken. It's also the reason why you may see more sparse conditions with the fine fescue over the bent and blue.
