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.
