IP Tables and TCP/IP rapper

If  I configure TCP/IP wrapper and iptables to block port 80.  When packet comes in which one will reject first? or which one detect first?  I am just wondering.

Since iptables is a firewall,  would say iptables.
Iptables will  reject first, tcp wrapper works kind of addon to the service is working;  

iptables will filter and if an ip is not allowed to connect will detect as a port closed and tcp wrapper will appear as port opened but as soon it validate is not allowed will disconnect it.
yes, IPTABLES because it is transport layer security and participate first in DAC security model.
