RN104: @mdgm-Benefits of factory reset under firmware v6.2.x

I can't quote the specific post but I'm sure you replied to one guy having problems with his RN104 that a v6.2.x factory reset did something over and above a standard upgrade, on the lines of the file system changes in v6.15.

I'll do a factory reset on the new unit as there's nothing there to change. On the working unit I have the alternate options to just upgrade without reset or stay with 6.17 as it's been running without any of the problems people seem to be having on the newer firmwares. Downside is if I do have to upgraded/factory reset in future there'll be a lot more data to move around then.

The real question is whether there are improvements that would be worth backing up and restoring the data on the existing unit. I have no problem doing that if there are long term benefits, I was just wondering what those benefits might be as the reset option was specifically recommended.
