Either you want the enhanced battlecloak or not. If you want it, B'rel is your only option.
Otherwise, Fleet Norgh. It's ludicrous that they charge you 4 fleet modules and require high-tier shipyards to get the fleet Hohsus BoP with JUST a single console more. A console doesn't make that kind of difference.
A Boff slot does. Get the Norgh. That boff slot allows more defensive capability, more healing, or even more offense depending how you set it up. Maybe you had a perfectly good build before, but you now can slot eject warp plasma and make it even BETTER (just one example).
EDIT: IMO the Fleet Norgh is the best BoP in the game. Second only to the Breen Plek Bresh raider. Only problem is it doesn't have a battlecloak. If it did, it'd be the raider for which KDF have been waiting a very long time.
Well the fleet Norgh has the best boff layout in the game. It can do anything fairly well. Not the best mind you (alpha stikes are the exception) but pretty dang good. Creativity is key. Kit bashing with the ningtao also makes it one of the prettiest ships in the game.
The Fleet B'rel is an odd duck. The only real thing it has going for it besides the universal stations is the enhanced battle cloak. The T'varo makes better use of the ebc for a straight damage torp boat or bomber. The common wisdom is to make it a sci heavy torp boat. It does better than most torp boats with this layout but that is selling it short. A little creativity with the B'rel can turn it into a very tough little ship. You can debuff, heal, cc, and do decent damage with it from the same hull while on the fly.
Both ships are outclassed in any one specific area but no ships are as versatile in all areas. This can be done on demand thanks to the bc or ebc. Mixing in or going straight dbbs will also add some utility. The fleet norgh also makes the best alpha striker around.

The B'rel is more flexible in general. Most important, you can cast heals on yourself without revealing. Ofc, you can heal yourself just as well by flying out of range, but that requires you to leave the zone of combat, which may not be desirable. Depending on the situation at hand really.
If you are worried about aux levels, you can either time your cycles (very easy) or use an aux batt if its an emergency (super easy).
The dbbs do less than a dhc build would on paper but in practice you are doing more damage as you can engage from greater range much more effectively. This really allows you to take advantage of the dbb's greater arc and less range degradation.
One is an energy weapon specialist the other is a torpedo/science specialist.
If you use energy weapons in a B'rel you're doing it wrong. Its a torpedo boat. Thats what the bloody enhanced cloak is for. Disabling that cloak by firing an energy weapon just makes the B'rel into a ship less capable than the freely available max rank BOP. You can also kit it for science since the cloak works with science abilities as well.
The Norgh is an energy weapon monster. The bridge officer slots and its guns give it a tremendous first strike advantage. If you are not putting full forward guns on this thing you're doing it wrong.
Limiting the B'Rel to ONLY torps is kind of weak. It's ONE use for the EBC. It's not the only use. As BoPs they are almost directly comparable on a 1 to 1 ratio. They are VERY similar. They have similar capabilities. Firing torps while cloaked is extremely limited and rather limiting your damage output regardless.
