The thing about visualizing moves when they are called out and seeing the board in your head is stuff for titled players mostly.
Otherwise I don't find the chess notation confusing. It's probably the least confusing method of notating chess moves. You say which piece moves where in the least amount of letters possible.
Once you know where all the squares are it shouldn't be that hard to understand notation.
The main reason it might be good to also know descriptive is so you can read old books that have not been translated to algebraic.
