Data Validation Reference vs noted

When trying to add a note to a cell on a worksheet, the most common way is to use the MS note feature.

I find that feature to be clunky, prone to bad editing, and really hard to see when the sheet is zoomed out. (We use it as a floor plan and booking system, not sure what’s the better alternative, taking suggestions!)

Other than users not seeing a ‘little red flag’ in the notes, is there any other pros and cons of using DV reference over notes? I’m the only one editing the sheet everyone can only view.
