I know this kind of undermines re-watch threads, but seeing as I have never seen
any Survivor before and know next to none of the results and will watch them in chronological order, I felt it should have its own thread
I have now seen Borneo, Australia and half of Africa so far, and will post my thoughts:
Borneo:
Borneo had such a beautiful location: definitely the best of the three I've seen. Survivor: Borneo was enjoyable enough before the merger, but what was most enjoyable was the devious plan hatched by the Tagi four, as well as Kelly's moral conflict: it was rivetting to see if there was going to be a rival to the Tagi alliance. The final episode is also fantastic. Such a wonderful end to the series.
Australia:
Australia IMO had better characters than in Borneo. It also had a more rivetting game play element I think. Tina, Jerri, Alicia, Elisabeth and Nick were all great

Some great villains too.
Africa:
I think Africa has a really good cast but the tribe swap really confused the series narrative I think. Like with the tribe swap which kind of broke down the alliances, and a terrible boot order of Linda, Silas, Lindsey and Clarence, I don't think I'm really going to enjoy the rest of Africa that much...
