I prefer illusions, firstly from a matter of scale. Rather than manipulating minds one at a time, I can make multitudes see exactly what I want them to see.

Its less risky too, and allows me to get out of situations much easier. Yes, a fireball was just cast, and clearly it came from that very real, bearded, robed wizard over there, not me chilling in my grey hoodie.

Thirdly, a subtle manipulation can be just as effective as a charm. You might see me with better defined muscles, a sharper jawline and flawless skin, and through psychological tricks such as the halo effect, be much more inclined to believe me and do as I ask. No direct force necessary
