Personally I wouldn't say UML on its own is flexible personally. The problem with UML is that you have to create your own scripts, etc. to control it. I know there are one or two ready-made sets of scripts (like UMLazi) that do that job, but I would say they are nowhere near as flexible as Virtuozzo/HSPComplete.
True, UML doesn't cost a fortune (or in fact anything), but when you pay for Virtuozzo, you do pay for stability and a full system for controlling the VPSs. With UML you have to rely on pretty much beta scripts, or create your own, which for many people will not have the time to do.
Just my 2 pence.
