I like TOTK's map. It's not really the activities there are to do in the map, but the sights. BOTW, with the same main map, is good but you had very few traversal options, making it too big. But you can literally build a helicopter in TOTK and fly everywhere, so you can actually explore it in a more timely manner.
The floating sky stuff was more disappointing than the underground, personally.
I haven't had any friends that are actually in my life since 2009.
