I think most of the universal consoles aren't very useful at all. Most of them are active consoles that have an ability you need to use, and they almost always have stupidly long cooldowns. I love the ones with passive bonuses though. Plasmonic Leech is probably the best one, in my opinion. Assimilated Module would be the second best.
I would have bought the Long Range Science Vessel Refit for the Nadeon Detonator, but I'm not wasting a console slot for something I can only use once every two minutes.
