YMMV, but I think one of the main drivers of OpenStack is that it can be modified, because it's open source.
IE, if you're Verizon / AT&T / T-Mobile, it's valuable to be able to modify the product to suit your needs. I did some work on an OpenStack project a couple of years ago where the client wanted to leverage some hardware that was absolutely cutting edge. Literally so new, that engineers from the hardware vendor were involved in tweaking and optimizing things.
Try doing that with VMWare; it's impossible. With OpenStack, there's nothing stopping you from modding the product to suit your needs.
Obviously, this works particularly well if you're running hundreds or thousands of servers and you can justify the investment. If I were only running a few dozen VMs, OpenStack is probably overkill.
