Having spent a fair bit of time with the
Canon system it is sort of second nature to me now for the
limited times that I need to access the menu banks.
Once the menus are set to your preferred defaults most actions that you need to perform are done with buttons or dials and easily accessed and remembered. That is more true of the better bodies than the cheap ones.
Having said that, in the course of helping a few photographers with their cameras and settings on
Nikon bodies I found the menu system fairly logical and straightforward to get around and I wouldn't go near to saying it is better / worse or harder / easier than the
Canon system.
