you just need to decide what do you want to do in your CAP.... if you want to be superieor fighter killer or bloody cap killer. For each way you need diferent equipmnet. You can be also combination of both but you need to know what to do.
Point of this is... antifighter cap is useless against another caps, anticap cap is useless against fighters - how to deal with that? Fly with friends.
Universal cap is weaker than specialized but have fair chance against both threats but you must know what to do... if you dont, maybe you just cant fly in cap;)
My personal utopic idea:
Limited numbers of caps and for official fractions only... (something like Red hessians 1 battleship, 3 cruisers, 6 gunboats..... RM 3 battleships, 6 cruisers, 12 gunboats etc. etc. ).
SN only as shiled buster and nova torpedo as BRUTAL.... repeat BRUTAL hull buster (300k?).
