I tested a lot of collaborative online project management services with a native Gantt display. Planzone was the only one I found. Moreover, it is one of the few to offer a torough, visual, multiproject view at a glance.
And with the incoming version (now in beta), Planzone just gets better : easier and more flexible way of linkind tasks, better and more modern ergonomy.
