Access list rules might force the switch or router to process-switch more packets/frames than it would otherwise, reducing the device’s effective overall traffic capacity. Intrusion detection, reporting, and avoidance capabilities of an embedded firewall are likely inferior to those of a dedicated security appliance.

What are the benefits of using firewalls with ACLS?

Firewalls enable you to configure global ACL lists on top of them. Firewalls are stateful and you could write custom rules (upto layer 7, like say blocking packets from a certain VLAN or preventing a certain command to be run on the server) on top of the regular functionality.
