There are certain events on higher difficulty in which the bosses will mull a specific type of turn skip. Generally the effects will be the same, but if that type of turn skip is nullified it does not turn skip the boss.
In the case of specifics for PVE, last DRV (first DRV since 8.0 update) the elite boss nullified Paralysis and Sleep, so Faint was recommended for last node (4th battle) only. Tower event (current event) nullifies Paralysis, so Sleep and Faint are recommended.
In terms of pvp, there aren’t any specific nulls or limitations to what type of turn skip you can or cannot use. The skill nullification cards that players have access to are limited to “nullify any skill”, “any attacking skill” or “any non attacking skill”. So depending on what you run, for pvp it shouldn’t be a big concern.
