Two situations where Sirrush might be better comes to mind (there might be others too):

1. Against tramplers.

2. Diversify your army. Opponents would expect skelly spam supplemented by other undead (Bane Lord is an obvious choice) and might spam dust to dust in addition to banishment. Sirrush's speed (relative to other C'yis units) also gives you more battlefield options.

BTW, adding equipment to Bane Lords add to its cost significantly and it would still be vulnerable to anti- undead spells. There comes a point where it would not be cost effective.
