European is a good traveller.Welcome to the forum, radheshthe.
Please tell us which you would use and why. We need your input in order to assist you.
I would agree and say however that if you use language like that, you might create an amusing vibe to an article. Probably because mocking that manner of speaking from formal "travelogues" and such has been done, such as with cartoons. Go watch some "Goofy" cartoons. A quaint throw-back to "earlier times" often comes off as amusing....
Having said that, though, "The European is a good traveller", although correct, has a rather old-fashioned, 1930s travelogue sound to it. I think we would much more naturally say "Europeans are good travellers".
