Hieracon vs. Triton: Tower III Key farming

[JMP3]

Which is better?  Pluto's Dark Sector Excavation seems to be better for getting fusion cores, but in the few times I've played there over Triton, Neptune, I've only gotten T4 keys.  Did I have bad luck, or do T3 keys not drop there?  I've looked on the Warframe Wiki, and I can't seem to find a drop table for Hieracon, Pluto, as Dark Sectors are their own tier.  Help would be much appreciated, as I'm trying to rebuild my supply of Tower III Survival keys after using about 7 of them in my quest for Saryn Prime.

No, It does drop T3 keys but less so than T4's. If you're mainly interested in T3's then Hieracon is not the best place to be.

Only 7 in getting Saryn P? Wow.

I am pretty sure Hieracon only drops T4 keys, since its a dark sector.

You misinterpreted what I said.  I don't have Saryn Prime yet, but I've done 7 40 minute survivals trying to get her.

Try Zeugma Phobos.  T2 and 3 keys, easy.  I take my Vaub and just do repeats of 300 cryotic.

I've gotten T3 keys on Wendell, Phobos. But be aware that they also drop T2 keys.

Lillith Europa, bring a SP Mag and you're good to go. T3's seem more common than T2's there imo...
