Is the left/right, creative/logical divide of the brain an outdated simplification, or a useful model?

I don't know where I've got this thought process from, but I think I learnt that the brain maps the 'yin and yang' of creative logical in a much messier way than simply left right? What is the current understanding of the brains functioning areas please?

The logic versus creative seems to be out of favor and kind of had left a bad taste in the mouths of researchers based on how it was popularized. But there's a researcher (Iain McGilchrist) who had proposed that the division is more like "big picture work" versus "details". The left hemisphere handles the really detailed stuff, the right the bigger ideas. He has a book, _The Master and His Emissary_.
