Asians, Europeans, Americans, African, Arabs as individual groups of ethnicity are too diverse and different to categorise and group up because these so called groups depending on the geography cannot be regarded as actual groups in reality. Because within them we can further group them by the nationality and still by the appearance or the look factor. Cos some countries has a wide range of people who a very different in look.
So my suggestion is that the question is too wide making it difficult to give a pin point answer. Therefore i must say humans like the look and a good body figure..and not mostly the ethnicity or nation. But at the same time should mention that some groups of people have more better looks and beauty.. Meaning that though Western people are well built and stronger than that of asians there are certain areas of western countries where some group of people are much more attractive than other... The same goes to Asians... People who has the look of Malaysians, Phillipino, has better look than most of japanese, chinese .... Also Nothern indians looks are better than that of sounthern of india and those countries in the indian ocean...
Asking about like must be concentrated and narrowed to liking of specific area or trait... be it religion, looks, i.q, etc...
