I think 2 is the most interesting and classy design. the angled chin is aesthetically pleasing and comfortable for your hands, and the compact 75% with separated F row is the nicest design. Exploded 75% is just bandwagoning on the popularity of the satisfaction75 and all the imitators after it, and lots of people are over that layout now because it adds too much bezel on the bottom where your hand rests. Just my 2 cents
