Oh, I guess we don't have that yet. The current best are:
#1 Health: Bardock SP (712,774)
#1 Strike Attack: Super Trunks (66,850)
#1 Blast Attack: Super Vegeta (63,724)
#1 Strike Defense: Android #17 (45,416)
#1 Blast Defense: Android #17 (46,221)
Interestly, without 398% soul boost SSJ Vegeta has #1 Strike Defense.
Above stats are calculated at max Level/Z Power/SB, but you can check their stats at lower limits on the character pages.
I'll get started on a site tool for a stats ranking list.
