F-16 and F-18 are both quadruple redundant channel FCS. F-18 has spaced linkages plus another direct connection on top of that. Both have slightly inferior digital FCS programs that back up their analog ones. I don't know much about the F-15/F-14 generation but it's along the same lines of design. Complaints about these new fangled computery whiz jets have been out of date since 1979 or so. I mean how much of an oooooooollllldddd maaaaannnn do you have to be to still be wringing that bell? FBW was new, then disco happened. Give it up, FBW won. It's better. Yes F-22 and F-35 are FBW. My understanding is F-35 is the first "open cycle" FCS which doesn't do canned control response but actually looks at the feedback in real time. F-35 also has electro-hydraulic actuators so everything's electric until the last foot where it becomes hydraulic so there aren't fluid lines running around everywhere.
