In my opinion, I will definitely select Fusion rather than Parallels, it is because Fusion more selection, and if for anyone want to expand to use VMware products, Fusion is the only choice for you, Because from Parallel, you cannot install the EXSI, Means you cannot install the host and create the virutual machine. but for Fusion it is very easy to use and add it. and Also Good networking setting and preference as well for users. What do you thinks?
