Whichever one feels right to you. I was in the 82nd, and wouldn't change that if I had the opportunity to go back and change that decision. I'm sure a lot of Marines feel the same way.
450,000 10 Infantry Divisions,1 Airborne Division and 3 Marine Divisions
No, Australia does not have a Marine Corps. This may be due to the following reasons: 1. Many Countries merged their Marine Infantry with regular Infantry years ago. 2. Australia's armed forces number less than 60,000, therefore Australia probably cannot afford to have a Marine Corps.
Of the list that you have provide, the marine corps infantry is the best.

The length of United States Marine Corps School of Infantry depends on the specific Military Occupational Specialty (MOS) that a Marine is training for. As there are many different MOS's, there are many different lengths.
Army...
A marine brigade is a formation of sailors and marines. A brigade consists of 14,500 sailors and marines around an infantry.
That's a decision for you to make. It all depends on what you want out of it, perhaps where you want to be stationed, etc.
A Marine Gunner serving in the MOS 0306 (Infantry Weapons Officer) is correctly termed a Gunner.
After bootcamp you go to your first unit. You qualify to be a seaman or fireman and learn about the boats you use. After 6 months you put your name on a school list of your choice. The wait for school is 6 months - 2 1/2 years depending on what school you choose.
Airborne is an Infantry unit that has the ability to deploy by air to the battlefield. Marines (if you are just talking about their Infantry) are an Expeditionary group that deploy by sea and work as the Infantry of the Navy. Rangers are a Special Operations Capable group that have the ability to deploy by Air Sea or Land in any part of the world within a few hours notice. Marine Corps Recruits go through Bootcamp and Army Recruits go through Basic Training, although they are very similar Bootcamp is longer by a few weeks and is said to be tougher due to the mentality that EVERY Marine is a Rifleman first. Becoming Airborne is an Army Special School that is Volunteerd for by recruits if they are in Infantry and have the abilities to become Airborne. Rangers are only a part of the Army although some Marines are invited to attend Ranger School. All Rangers must go through basic training as well as Airborne School on top of Attending the Ranger Assesment Program before being allowed to attend Ranger School. Ranger School is said to be among the toughest training available in the Military. Ranger school is an Intense 61 day training program that is divided into 4 phases that pushes candidates beyond their physical and mental abilities. There is an extremely high failure/dropout rate but for those who do graduate, they are considered are among the elite and can be compared with some of the worlds elite special forces groups such as the Navy SEALs MARSOC Marines and Green Berets. - - - - - Airborne doesn't necessarily mean infantry. The 82nd Airborne Division at Fort Bragg has every kind of unit you'd find in any other division--engineers, artillery, supply--but every soldier in the division is airborne. You've got to look at the service past your initial training...and either the 82nd Airborne or the Rangers would be better than the Marines because the Rangers and 82nd jump into battle, and the Marines walk.
A soldier is someone who is in the army. A Marine is a person who is serving in the United States Marine Corps. What you are probably referring to is an infantryman or someone who is a member of the Marine Corps Infantry.
