Really depends on your goal, pal.
You're basically comparing a glacier to a meteor.
Sej is better if you need AoE, Vi is better if you want to focus single targets.
Vi is a much stronger champ right now but they're not really comparable.
Vi is a pseudo assassin who specialises in locking up a single champ and dealing significant damage to them while Sejuani's an AOE based lock down tank who can deal decent damage in an AOE.
Sej 2.0 is Amumu who is a superior champ to her at the same role right now.

need a tank? sejuani with CC that can be a frontline need a fighter to lock down one slippery target and team already has a tank? vi
Sej is beefier and better in long-term engagements, and even though CC hurts her performance, it's not nearly as bad as it could be.
Vi hits harder and is better in short-term engagements, so she tends to be worse off when hit by CC.
Take your pick based on what makes your team more effective or their team less effective. Don't forget that the former is dominantly magic damage, and the latter entirely physical damage.
Bristles is the best champion.
