Currently season 5 has aired as of this writing, I have never seen the show, but wonder what items that teams most often choose to bring, from the list of 40?
According to the Survival Skills Alone Gear List, the most frequently chosen were sleeping bag (100%); ferro rod (100%); fishing kit with line (96%); 2 quart pot (91%), knife (89%); ax (87%), saw (85%), food (77%).
After that there's a significant drop before the rest, which include gill net (45%); paracord (43%); 12x12 tarp (34%); Bow and 6 arrows (34%); multi-tool (26%); wire (26%); bivy bag (17%); water bottle (15%); frying pan (11%).
That site sets them out two ways. One is a graph, and the other is a breakdown of each year.
