It doesn't even make that much sense to compare them -- these techniques are bolt-ons - more or less useful practices to make do with the challenges inherent to a conventional structure. On the contrary, Holacracy is a new meta-structure for how power is distributed, how decision-making is distributed, with different channels available to effect changes - a new "social operating system", really.
In my experience, having my manager use techniques like SCARF to "better reward me" is nowhere near as powerful and empowering as having no manager to solve my problems, because there is a system that allows me to address them myself.
