I had the same question. However, I then read a message from the manufacturer AVM somewhere that the difference originally only affected the software anyway and has since become obsolete due to new firmware updates. So in my opinion, it makes no difference which version you buy.

The AI-generated answer from digitec seems to be from Gemini. The problem is that Gemini says that the AVM FRITZ!Box 6860 5G Edition International is the more recommended version for Switzerland. However, Copilot, for example, claims the opposite, that the AVM FRITZ!Box 6860 5G is the more recommendable version. So I ask the NI (natural/human intelligence) ;-)
