In my experience, linuxbridge works very well and is a lot simpler to
set up and configure in an environment where other software/hardware is
handling the general network configuration (especially if you have
experience with using network bridges on Linux KVM deployments).

I would go with linuxbridge (especially in a straightfoward setup)
unless the additional features of openvswitch are needed.
