I think until 1970, the greatest bowler of all time conversation was entirely a two man show, Sydney Francis Barnes vs Tiger O'Reilly with Barnes winning out by a small margin. Lindwall, Davidson, Trueman and Bedser all went very high but quite never reached those two.
In the 70s and 80s, I reckon Lillee and then Marshall got added to that debate, not because they were better bowlers than Lindwall or Trueman (well, Marshall was, Lillee wasn't imo) but because those who saw Barnes started dying, O'Reilly still in the conversation.
In modern times, it seems Barnes has maintained insane reverence due to statistics, O'Reilly very highly among knowledgeable circles, Marshall is regarded as the GOAT with McGrath, Warne, maybe Murali in the chat. Lillee seems to have fallen out of the race.
