I think any hair is hard to maintain if you dont know how to work with it
My friends daughter is a 3b and he kept cutting it because he didnt know how to deal with it, took me 15 minutes to detangle her hair. He thought I was a miracle worker.
Not so, you cant approach anyones hair thinking that its going to be a piece of cake because its looser or tighter.
Im a 4a/b and have no issues with my hair, NOW! Time and patience is the best tool anyone could have.
