Klosterhalfen has the fastest 3000m, the 3rd or so fastest 5000m (as a solo run) and the fastest half marathon of non-Africans of all time (more than a minute faster than Sisson). And a worlds bronze medal in sub 14:30 (and all this but the half was before supershoes). Unless you count marathon as something superspecial (and because of supershoes that help considerably more there than on track, I'd rather not), I'd also say Schweizer is about as a good as Sisson, Monson as well. (Batocletti does not belong here, she had a single outlier good race at the Olympics but we don't know if she will be able to get back to that level again.)
