Breakdown of the imdb scores for each Doctor from reddit.
In terms of public perception the three worst runs from most bad to least are
>Whittaker
>Colin Baker
>Sylvester McCoy
Conversely the most excellent runs that Doctor Who from most to least is
>Tennant (14)
>Tennant (10)

14 is that high because he only had three episodes, and it's the same with 8 having 50% as Night of the Doctor is being counted so the rightful third place is Eccleston.
