Wilf no contest.

Sarah is easily the weakest here imo. I’ll go with Jamie because he’s more of a companion than Wilf, but man will I feel bad.

Also Jamie is more likely to beat Sarah than Wilf is.

Wilf, but I’ll always love Donna

Wilfred was awesome. Sad he had that fate of forcing the tenth doctor to essentially kill himself though (but 10 did have a long season)
