Enclave is really good for farming Omega-49. Rule-wise this system is still Bretonian yellow zone and therefore it's cool & good place for Enclave to farm. Of course, keep an eye on Coalition and BAFs, they'll try to gank you, but this is nothing new for the server
Corsairs are good for farming spot in Zeta, but be afraid of Core. Same issue about ganking
Nomads. Really dude, these squids are good for farming Omega-49 as it is in Omega ZOIs as well, but expect to be ganked by literally everyone
Enclave is also good for farming Burgundy, but 50% nerf made this zone really sh*t
Dunno about the rest of spots as I don't really care about other places
