"England averaged 6.49 runs per wicket less than Australia in this
series, but still won. This is the biggest runs-per-wicket deficit
ever overcome to win a Test series."
I think it is easy to guess no. 2 on that list - Eng-RSA '98.
England lost on virtually every statistical aspect, but played their best

"Australia dominated just about every statistical facet of the Ashes series
in England, and still, unfeasibly, failed to retain The Urn. They outscored
England 2886 runs to 2869, from eight innings to nine, and lost just 71
wickets to England's 84.
Individually, they boasted six of the seven leading runs-scorers in the
series, with Andrew Strauss, who topped the rankings with 474 runs, the only
England player in the top seven. And they boasted the three leading
wicket-takers in the series, with Ben Hilfenhaus, Peter Siddle and Mitchell
Johnson the only bowlers to claim 20 wickets or more."
