Im watching all of them right now, i just started yesterday joe1110
Im watching 7 first, then watching them backwards (6, 5, 4, 3, 2, 1) then I'll start going forward again from season 8 which is all stars
Season 1 is different than every other season, I'd recommend watching Season 6, 7, or 9 first to see if you actually like it. Then go back and watch Season 1 before you watch All Stars since a lot of people come back from that season.
but I think Australia, Pearl Islands and Vanuatu are all great
