A good film scanner will beat any flatbed hand down. Dmax will probably be higher, the film if it isnt held flat, will have an autofocus facility andthe colour reproduction is as good as it gets. I have a Nikon LS5 with a max resolution of 4000dpi and a dmax of 4.2.
The downside is, unless you can master 3rd party software, Silverfast etc, (not always straightforward to load.) or you have a computer running the Windows XP operating system. you are in difficulties. I run mine on a cheap 2nd hand laptop with XP save onto a flash drive and transfer to my main computer with Adobe CC. You can also scan with NEF - Nikon's RAW file which can give far more detail than say Jpg or TIFF.
The superb Digital ICE cubed facility is in my mind unsurpassed in removing unwanted dust, scatches etc. That alone is worth keeping it running.
