For businesses without very strong tech teams but with a need for lots of VPN accounts, cisco webvpn has long been popular, as it does all the things well that the things you mentioned don't: It has good stories around user management and access control. There are literally millions of people able to configure it well enough to work. It has an excellent reputation for stability and security among it's client base (which is not the same as actually being very secure, mind). It has good (albeit expensive) commercial support. It works well with most desktop and mobiles OSes. It's easy for non-technical users to use it. Etc, etc.
