Can someone please tell me in which situation would I use TCP wrappers over IP tables or vice versa because right now I don't see a reason to use it for my ssh server if I have ip tables implemented . I have read books and online resource stating that I should use TCP wrappers for ssh server just don't see why I would if I'm using IP tables it seems to me that IP tables do the same thing just control access on a more broader range of services and protocols.
PS. I read all the similar threads regarding TCP wrapper none help me.
In some situations they could be mutually exclusive. Example:
Host is running sshd.
tcp wrappers support is compiled into sshd.
iptables/netfilter is also enabled.
There is a need to restrict access to sshd to the 192.168.5.0/24 subnet.
An iptables rule could be used to allow access to tcp 22 from that subnet. Or, if no packet filtering is done on tcp 22 at all, an appropriate tcp wrappers ruleset could allow only that subnet and block the rest.

But you would still be using iptables for other ports I'd assume
