Interesting. Those are all great cameras. Although I haven't tried them, if NG is recommending them I bet they would all be good for travel.
I usually travel for business so the smaller and lighter the better.
I used to take a an LX1, then LX3, then switched to Canon S95, then Canon S100, then to RX100 for a few years. Now it's the Coolpix A!
Notice the trend for a larger sensor, just like the camera manufacturers are doing.
If I am travel with time to focusing (pun intended) on photography, then a Domke bag with the Nikon Df and an assortment of lenses go along. That happens less frequently than I would like. And then there is always the iPhone when nothing else is at hand.
