Simply put ESXi is exactly the same local feature set as ESX server.
So you get all of the useful stuff like transparent memory page
sharing (memory deduplication), virtual switches with VLAN tagging,
and high performance storage I/O. For free. As many copies as you like.
But... You will need a vCenter license and then by server (well, by
processor) licenses if you want the advanced management features like
live migration of running VMs between servers, fault tolerance, guided
consolidation etc.
Most importantly, ESXi is a bare metal install so you have a proper
hypervisor allocating resources instead of a general purpose OS with a
Virtualisation application.

Uhhh - for an unmanaged server you can use ESXi for free. Identical
server functionality, just requires licenses if you need
multiserver features (ie vMotion)
How does ESXi w/o vMotion, vSphere, and vCenter server stack up
against VMWare Server? My impression was that you need these other
pieces to make such an infrastructure useful?
VMware server doesn't have vmotion. There is no such thing as
"vsphere", that's the marketing name for the entire product suite.
vCenter is only required for advanced functionality like HA/DPM/DRS
that you don't have with VMware server either.
Are you just throwing out buzzwords, or do you actually know what
they do?
