The only chorus that has ever given me GAS is the DC-2w. Some bassist on Reddit posted a massively detailed thread as to why they liked it and what really helped sell it to them was that you don't really hear the LFOs, and that sold me on it too (though I haven't actually bought one so I guess I'm not really 'sold' on it

). That said, you probably want to run it in stereo to really get that result. What appeals to me about choruses is the spatial effect and duplication, not the wobble or synthetic tone. Which is why I don't run chorus, because I already run two channels and though I tried to run one of them in stereo, it proved to be a pain in the end.
For dirt, a few recommendations: GroundFX Burning Sunn is my dirty centrepiece. Seriously the best pedal I've ever owned. Anything by Dunwich Amplification (now sold by Magic Pedals) should work well too. Their pedals are mostly improved clones of classics like the RAT, HM-2. If you want something more modern, I am not the one to ask. I am of the opinion that any dirt pedal conceptualised after 1993 can't doom. All they know is chuggachugga, clean blend, dweedledidee, crossover, clankaclank, eat hot chip and lie.
For noise... How about an EHX RTG into a fuzz?
