Given only the tech stack, it can go either way, depending on whether the implementor takes the easy, lazy route or actually puts some thought and hardwork into it. The problem is, as per good old Sturgeon's law, 90% of sites take the lazy route, and end up with tangled monstrosities that look like offerings to the Flying Sphaghetti Monster.
(Also, it's interesting how quickly 'cool new tech' can become 'Enterprise' shudder when it's widely abused and misused.)
Not exactly any of these technologies, but it is using more javascript at least. I think the example is pretty awesome actually.
