Well, DB is a middle/lower top end set for ST and AoE. With a fair bit of recharge, you can put out BF+Attack Vitals, your most realistically attainable most damaging attack string. Personally, I love the set for its later animations, so not only will you do damage, but you'll look good doing it.
As for /Elec, it's a midrange set as well focused around QoL stuff. You will be essentially immune to end drain, have limitless endurance (after level 35), have slow resists, + recharge, Psi resists, a damage toggle, and last but not least, a sweet heal that also gives regen and reduces end use (notice a theme?). All that cool stuff comes at a price though. Your actual defenses rely soley on resistance, which although higher than most, won't get you as far as a combination of something like resistance AND defense in a swarm of mobs. End drain also doesn't scale well, so if you want to fight a bunch of say +4's and are expecting to drain 'em dry, forget about it. Also, you awesome heal is on a two minute timer, which after some recharge bonuses will be coming up around 45-50 seconds. All this means is that you will fly through missions set for +2-3/+4, but if you are looking for something to go against +4+8, I don't think this is the set for you.
All in all, DB is a great set that looks flashy, and /Elec has some cool tools that you can utilize to avoid the more annoying aspects of CoH, but as far as "balls to the walls" durability, look elsewhere.

this. I actually prefer resist sets, I find you get better layering since def is so much easier to get on IOs than resist.
the glaring problem here is you are left with no defense or resist debuff resistance.
Elec armor is better on a brute, assuming you arent going for a theme. the resistance wont be capped at 75 on en, and power surge will be actually useful for everything, not just pluging the GLARING toxic hole. The heal will be for more and the regen will be similarly more meaningful.
I'm thinking of rolling out another scrapper, but i would like to know the pros/cons of db/elec. any help?
