I prefer Ruby, Sapphire, and Emerald. They featured Hoenn, which is my all-time favorite region. Hoenn was quite special; all of its locations had something unique that set them apart. Mossdeep City had Space Center and was completely surrounded by water, Slateport had Slateport Market and Oceanic Museum, Fallarbor Town was the home of most farmers and had access to Contest Hall, Fortree had gigantic treehouses, Lavaridge Town had hot springs, etc. etc. d: Also, I really enjoyed the storyline of these games. I found it to be pretty interesting!
