I guess it depends on what your application is here. Hexaly primarily focuses on Routing, Packing and Scheduling problems, which have strong Combinatorial components. My experience with those type of problems is that Hexaly is in its own league above the MIP solvers, especially at scale. For applications like portfolio optimization or network design MIP solvers still fare a lot better.
