When I think about it, it's not really the region or species that I favor but rather certain oils in my collection that I favor over others; oils that just happen to be from a certain region and are done the way I like and not necessarily to say I'll favor every oil from that region.
The whole species/region thing was something I started to expand on in my response about kyara/kinam formation to @RobertOne. Not only will you find variation among the different species, you can and will find variation within a specific species. From a consumer perspective it's as @Ensar stated, more of a handicap than anything because liking or favoring one or several oils from a region may not confer to liking/not liking oils from that region as a whole.
