Its Leica, not "Lieca". And dont pay extra just for a name, thats wasteful and silly, and only people of questionable intelligence would be impressed by that. Leica compacts are just rebranded Panasonic compacts, just buy the originals.
Besides, Hasselblad also had a good name and they just effectively got bankrupt and got sold to DJI. Leica might go the same way, though they didnt acted as poorly as Hasselblad did in their final days.
There is no such thing as a travel camera. One can use any camera for travel. Whats talked about here is superzooms. Which certainly is one possible choice for travel, but certainly not the only one.
If I really wanted a superzoom, I'd pick a Fujifilm X-T2 and a Fujinon XF 18-135mm f3.5-5.6 OIS from the used market. That would be around $1200.
But, fun fact: I never want a superzoom. They are anything but a universal lens, since they are quite dark and slow autofocus. Most are also disappointing image quality, though Fujis 18-135 managed to transcend that. Its actually so good I would consider using it. Still dark though.
My actual pick for a travel camera would thus be a system camera and a couple prime lenses. For example, with Fujifilm, XF 16/2.8, XF 23/2 and XF 60/2.4.
About GoPro etc, really just take your pick. I have no special advice there.
