No it is not the same. Connection tracking just tracks the connection
and can decide whether a packet belongs to a connection or not, but does
no intelligent filtering. This is the same between FW1 and iptables.

Stateful inspection is implemented in netfilter too, using specific
modules, like ip_conntrack_ftp, ip_conntrack_h323 etc.
It is not as advanced as in FW-1, meaning FW-1 supports more protocols
and actually content inspection.
