ISO best hair multi-styler

I just tested the BaByliss pro styler out on myself but I’m looking to purchase as a gift to my mom. I have 3A hair on the finer side and honestly I didn’t like the results all too much. It doesn’t get all that hot in my opinion which I know is better for heat damage prevention but overall I didn’t not yield the results I wanted.

On the other hand, my mom is more of a 2B, on the coarse & thicker side so I’m wondering whether results would be better / worse for her hair type. Or what Multi-styler would work best for her. She curls & diffuses her hair a lot and blow dries, but she also has an old Revlon one step brush that she will use for blow outs sometimes. Any insight is appreciated!
