Be fair. It can be said they compete, but, due to their very different design priorities, they don't compete directly.
I don't think the benchmarks make much sense in this situation, unless you measure server utilization and performance guarantees (which is the dimension in which they differentiate themselves).
One could use LXC for completely allocating a CPU for some container so they can compete on one aspect. LXC still doesn't run on bare-metal and so can't take on the cpu separation for hardware accesses but there is a dimension in which they compete.
