Just sharing what i found regarding this.

OVS differs from the commercial offerings from VMware and Cisco. One point worth noting about OVS is that there is not a native SDN Controller or manager, like the Virtual Supervisor Manager (VSM) in the Cisco 1000V or vCenter in the case of VMware’s distributed switch. Open vSwitch is meant to be controlled and managed by third party controllers and managers.

For NSX with vSphere Logical switch is fine.

The Open vSwitch is mainly for the non ESXi platforms. The below is from the NSX-T white paper which uses Open vSwitch.

Open  vswitch is the initial switch which was developed by Nicra which was integrated with KVM hypervisors.

No.

"Moving forward, VMware will have a single virtual switch strategy that focuses on two sets of native virtual switch offerings – VMware vSphere® Standard Switch and vSphere Distributed Switch™ for VMware vSphere, and the Open virtual switch (OVS). "
