Combined, the two Australian motorsport personalities picked up 67 percent of the favourable responses in the annual survey.
The question asked fans to select the ‘best presenter/commentator in Australian motorsport' of 2021, with options from Fox Sports, Seven Network and various online platforms.
As it was in the last edition of the survey, Crompton narrowly edged out Larkham with 35.13 percent of responses landing in the former's favour.
Larkham was still close at 32.79 percent of the vote, but both were well clear of anyone else.
Mark Skaife claimed the third most votes, at 3.97 percent, while everyone else garnered responses of some number.
‘Crompo' and ‘Larko' were hard to beat on their combined 67 percent, but a wide selection means all of the remaining scores are single-digit percentages.
Notably, Supercars' Chad Neylon climbed up the ladder from 1.48 percent in 2020 to 2.17 percent of responders nominating him the mantle of best presenter in 2021.
Neylon had increased involvement in the Fox Sports coverage last year, stepping into commentary alongside Skaife for Supercars sessions during Crompton's health-related absence.
