If you have license for VMware HA I would re-evaluate the need for MSCS. You can lower the complexity of the solution by not involving MSCS and run your SQL servers as any other VM.
You achieve basically the same uptime with VMware HA. In an worst-case event of a power failure of a host, there will be a downtime on the SQL service, doesnt matter if its MSCS or VMware HA.
The one benefit with with MSCS is that you can do a failover to another VM server when you are patching the Operating System (the SQL service is still stopped/started and causes a short downtime). But for this you are adding more layers of complexity like MSCS itself and different disk setup and constraints.
