Do you think that making a comic/manga is exhausting?? or should i opt for making a light novel instead with some illustrations here and there?

hello guys i would really like to know your opinion about the idea of making a comic/manga. Do you think it would be extremely exhausting if done by one person drawing every single panel and on every page?

i have a story that i have developed in a long time that i really want to make wether into a comic or light novel. I have even designed most of it's characters and backstories too (My OCs).

What do you guys think which is an overal better option (or perhaps efficient?) for me to tell this story i have? Is making it into a comic better, or light novel is better?
