My personal opinion is that the best published version of the Realms for D&D gaming is, was, and remains the Old Gray Box (1987).
But it's why I was advocating (ten years ago on the Candlekeep forum) that the "Fifth Edition" version of the Realms should reboot the entire setting back to the standard of the Old Gray Box and 1357 DR, and then never advance the timeline in any subsequent tabletop RPG product. Let the Realms as a multimedia property setting (computer games, novels, whatever) do whatever, but don't back-import any of that to the TTRPG.
I was very distressed that 4e added 100 years effectively killing hundreds of characters. I would like to reboot to then too (which is where I started, box + hardcover).
Is handsome robs map from that time? this one : /faerun/
