Adamant has a few, like the Magnetic Screen which is an inferior shielding technolgy, but nice if you haven't researched shield tech (or you're an organic race which can't get shields for ships
)
AIC and Proportions have multiple levels of the unique techs, so while you need the ruins to get you started, after that you can improve on them with research... for instance, I think the Neural Combat Net starts with an attack/defense penalty but you can remove that with research, and the Massive Shield Depleter improves its rate of fire so you can fire it several times per combat at higher levels...
If I ever finish the Antares Mod it will have all the Orion techs from MOO2 as unique techs... I'll probably make them really expensive or tone them down or something because I can't put in Guardians to protect the ruins without using a custom map...
