Though the paygrade is the same (E-1), the recruit's general career path determines which recruit rate they are initially assigned:
Engineering Rates (e.g., Machinist's Mate) - Fireman Recruit (FR) - 1 Red Stripe
Aviation Rates (e.g., Aviation Ordnance) - Airman Recruit (AR) - 1 Green Stripe
All others or non-designated careers - Seaman Recruit (SR) - 1 White Stripe
The Seaman, Fireman, or Airman designation stays with the sailor until such time as they're promoted to Petty Officer 3rd Class (E-4), at which point a career rate has been chosen, and their rate designation is shown on their Rank/Rate patch. The stripe colors are used to denote the area the sailor is striking in (working toward), or has chosen for a full career path later.
As an example, when I first joined, I was a Seaman Recruit, having chosen Submarine Sonar as my career path. Since I was also in an accelerated career path, I left BT as a Seaman, and was promoted to 3rd Class after finishing Basic Sonar school, at which point my rank/rate was Sonar Technician (Submarines) 3rd Class.
Depends on your personal interest. But personally I'd say Boatswain's mate if you want to be a real sailor. Gunners mate if you like being around guns.

MOS would be most interchangeable with Rate in the navy. Rate is pretty much another word for job specialty as is mos. Rate may also be referred to as a NEC.

Not SSK3c, but SK3c is the old rate designation for Ship's Storekeeper, 3rd Class. The Storekeeper rate, one of the oldest in the Navy, has always used the designator SK. Today the rate/rank would be designated SK3.
