Stellar cascade needs spamming (must reach 100 damage to effectively hold the target) and is AP, not AN. So paralyzis is better against armored targets with low MR, and stellar cascade against unarmored with high MR. You also have a huge difference in terms of precision and AoE. Stellar cascades basically requires spamming and can affect many units. Paralysis with some penetration can get rid of a single nasty thug or SC.
