I find it to be more difficult. Especially if I can't pane the files in view comfortably (ie. beyond 2 or 3 it gets significantly harder to work across them).

Some frameworks or coding styles really lean into having lots of tiny files. That necessitates a more complicated directory structure for the project. Locating files eventually tends to requires search capability rather than being able to look through the tree in a sidebar.

None of this is "hard" per se but I find the opposite is nicer to work with typically.
