Skarner has a 2 second aoe 40% ms debuff on a 3.5 sec timer (but due to his passive, it occurs more frequently). Sej has a 3 second 70% ms debuff on an eleven sec timer. In addition to this, Skarner will frequently buy iceborn gauntlet because of his great ability to spam it and incredible CDR, mana, and mitigation scaling.

While I think Sej has the easier to use ult for initiating team fights, I would definitely give the nod to Skarner for actually disrupting teamfights better simply because he keeps his ms slow going forever and shrugs off damage better due to his shield.
