Your somewhat wrong ninjacentral has way better content than geek and planet, remuxes, untouched blurays encodes from cabal sites etc, id go look again if i was you. Also check out nzbfinder and tabularasa you gan get 5 downloads free on them all just unlike geek forcing you to pay after 2 days for normal scene releases available from rarbg.
Edit oh and usenetcrawler. planet and geek not as good as you think.
Althub, abnzb,simplynzb,nzbcat all **** they index normal crap and zero upload teams as ninja, dog, finder,slug tabula, planet just scrapes other sites with few unique posts due to user uploads.
For best quality will be, ninjacentral, omgwtf, dognzb and nzbs.in, this sites have best p2p content from ptp,btn,hdb karagara , private warez and topsite
Finder, slug, tabula,geek planet and nzb.su (.su plently incompletes due to no par files generated) 2nd tier indexers, for sure alternatives if you cant get into the top tiers sites mentioned above
Rest just stay away
