People often perceive the difference between XenDesktop and VMware Horizon™ 6 (with View) in terms of the scope of their capabilities. VMware Horizon 6 (with View) is a one-size-fits-all solution designed to deliver VDI and nothing else. XenDesktop takes a broader, more flexible approach to desktop virtualization, acknowledging the considerable benefits for both users and IT of delivering desktops and apps in the right way for each use case.
Citrix is an industry leader in desktop virtualization in part because of the breadth and depth of the options it provides for going beyond VDI. Users prefer XenDesktop over VMware Horizon 6 (with View) because of the superior efficiency and user experience this flexibility makes possible.
