What is the main difference between the two? Advantages? Disadvantages? Why would I want to implement NAC over ACS? or ACS over NAC? Which is better?

I supposed you are referring to Cisco use term on NAC and ACS.

NAC serves a network enforcement point supporting 802.1x. It offers Authentication, Authorization and Remediation

ACS also does the NAC part and further provides TACACS/Radius support for network device management. However, it does not offer remediation.

You can check out the comparison details

There is in fact Identity Services Engine (ISE) which is probably what you should be exploring too

ISE takes on the features of NAC appliance, ACS 802.1x, Cisco Profiler and Cisco Guest server
