Preemptive worth for /Elec armor? Which tree?

I was thinking about crafting preemptive interface because it makes sense for my elec armor brute, both for the end draind and for the energy DoT.
Was wondering if I should go with the T3 Total radial 75% DoT or the end drain is worthy.
Thanks in advance!

A while back I did a quick look at the effects of interface DoT at the different probabilities. The shift from 25% to 75% is rather remarkable.

25% -> 75% chance of NO DoT, 18.75% chance of 1 DoT, 4.69% chance of 2 DoT, 1.17% chance of 3 DoT, 0.39% chance of 4 DoT; average effect of 0.33 DoT effects applied (13.39 x 0.33 = 4.45 damage on average)
50% -> 50% chance of NO DoT, 25.00% chance of 1 DoT, 12.50% chance of 2 DoT, 6.25% chance of 3 DoT, 6.25% chance of 4 DoT: average effect of 0.94 DoT effects applied (13.39 x 0.33 = 12.55 damage on average)
75% -> 25.00% chance of NO DoT, 18.75% chance of 1 DoT, 14.06% chance of 2 DoT, 10.55% chance of 3 DoT, 31.64% chance of 4 DoT: average effect of 2.05 DoT effects applied (13.39 x 2.05 = 27.46 damage on average)

IMO, if you're surviving well already, go with the higher DoT.

How does the DoT dmg compare with Reactive, Spectral, etc? Is energy highly resisted by endgame mobs/AVs?

I have Reactive at the moment, both because of the high dmg and because it fits fairly well with an electric concept (sparks/arcs set stuff on fire). However, the end drain/energy dmg would fit even better, and I love keeping enemies blue bars empty.
