which one is the most fulfilling career between dental hygiene and respiratory therapist , like the one not everybody hates

Hey guys, so I'm planning on going into the healthcare right? Cause my parents wanted me to do law, but I don't really want to do it. Because it's not really my thing, so I just choosed healthcare cause I feel like it might be the only field I could actually tolerate. But I just don't want to see myself doing something that I might also hate in the future as I said with the law you know? So my question is, which career between dental hygiene and respiratory therapy is the most fulfilling, like the one not everybody hates.

Edit: also thank you for all of you answers

English is not really my first language but I'm trying so pls don't take offense at me.
