This is largely opinion. If SanDisk does it one way or another, theres going to be a set amount of people who want it the other way. I personally like the ID3 tag method. Because I can still accomplish what you describe using playlist.
Sures its an extra step, but it lets me do everything you accomplish with filetree’s AND Id3 tag. Even other large manufacturers are following suit with the same method.
