The remnant of SN1006 pales compared to the Crab. I think that the simplistic
reason is that SN1054 was a Type II event, involving a huge progenitor star.
The slowly declining light curve of SN1006 constructed from Chinese
observations suggests a Type I supernova, in which much less mass was expelled.
Likewise for Tycho's and Kepler's Stars (SN1572 and 1604), in which there's
not much left of their remnants.
