Not to me
I guess that all these lists except AEGT are blitz and the gap in AEGT is the
smallest.

Ruffian may be better in blitz than Aristarch but not better than it at longer
time control.

I believe that the rating lists that you  give are based on ponder off games.
WBEC is based on ponder on games and I read
the following rating list by Frank quisinsky in the arena forum based on ponder
on games at 10/40 time control.

4 Aristarch 4.50                 : 2685   54  53   130    58.1 %   2629
8 Ruffian 2.1.0                  : 2657   58  45   130    53.8 %   2630   33.8 %
