I jumped onto the FreeBSD train a year ago and needed some virtualization tool for my job. A started using bhyve and must say that I am quite happy with it and don't plan to move to any other tool soon. Not sure how it compares to other tools performance wise but it does the job for me.
I've really wanted to try bhyve but the lack of hardware passthrough support (PCIe GPU passthrough in my case) compared to KVM keeps me from it as of right now. Looks really good though.
