Pick based on what you enjoy, not what others consider the most useful, otherwise you may not be happy in your future career.
1) Analytical. Do you enjoy repetitive work while sitting in front of a ICPMS, GC, etc, with the majority of wet chemistry you do being dilutions and standard preparation?
2)Physical. Enjoy extensive calculations, computer work and software modeling? I know some physical chemists who have not done a reaction on the bench in 20 years.
3)Inorganic. Definitely do bench work, and usually ends up working with catalysts or nanomaterials. Is this what you enjoy?
4)Organic. Lots of bench work again, usually end up working drug discovery or natural product synthesis. Is this what you enjoy?
Of course these are overly simplified, but most of the time these groupings are correct.
