I have two KDF Capt's, 1 Eng and 1 Tac. DHC's have a higher DPS rating but it depends a lot on your ability to keep the target within the 45 degree firing arc. In my Hegh'Ta Heavy BOP that's hardly difficult, even without an RCS console. In fact an RCS console on a BOP is "gilding the Lily", so to speak. So my BOP mounts DHC and DC fore and turrets aft. I'm not a fan of torps. They're fine for some and can be very effective but I find that a well built beam/cannon boat works better for me and I don't have to devote consoles or BoFF abilities to kinetic weapons. However I've seen torpedo boats in action that were also quite effective (and they can devote power to shields that I can't). To each their own, try different things and find what works best for you. My Tac also flies a Fleet K'Tinga retrofit. Something of a cross between a Raptor and a Lt. Cruiser. On that I mount beam arrays and dual beam banks fore and beam arrays and turrets aft. While turrets have low, overall, DPS they have a 360 degree arc so are always firing. With an RCS console the K'Tinga is actually quite nimble but still spends enough time broadside that I decided beams were better than dual cannons. BoFF abilities are critical, especially shield and hull heals. It also depends a lot on whether you are building for PvE or PvP. Overall PvE will be easier than PvP but some builds that work well for PvP are not as effective in PvE. The primary thing to remember between them is that in PvE the NPC's miss a LOT more shots than your opponents will in PvP.
