Less usable in terms of ease of configuration and use? Or reliability? In practice netdump's non-interrupt-driven polling mode proved fairly reliable but it seems to me kdump provides more reliable dumping than netdump. Because you're performing the kdump from a reliable new dump kernel (provided the initial kexec transition to the dump kernel works properly).
