There is no such thing, when you talk about the switch. The ONLY differences I know of is the power cable itself, and writing on the package. Got NTSC games and want to play on a 50hz PAL TV in your hotel room in Europe or Australia? No problem. Adjust your settings (if you even need to). You can simultaneously have accounts from ALL e-shops on your system at once. Every. Single. Switch. is. Identical. (internally, anyway. Not talking about different colored joycons.)
