They're three different firewalls, but they have similar capabilities. Not sure whether IPF is still being developed.

It's hard to say which one is better, but most users use IPFW or PF. I'd recommend PF though.

Use a block all rule, then open up the ports that are required. For DNS it's 53, and 67 and 68 for DHCP.
