A few points first:
Enlisted personnel are the "workers". We stand watch, opeate the equipment, perform the maintenance, keep everything clean (there is no janitor service in the Navy).
Officers are generally the program managers. They are "in charge", for what that phrase is worth. Officers have the administrative power, are responsible for the actions of their subordinate sailors, and, in the case of the Commanding Officer, are responsible for the actions of every single sailor under their command, as well as the safe operation of their multi-billion dollar warship.
Enlisted pay is lower than an officer's pay, given equal amounts of time of service and educational background. Higher ranked enlisted personnel with longer tenure on active duty make more than recently commissioned junior officers (JO's), as they should. For example, referencing the current payscale,
http://www.dfas.mil/militarymembers.html , gives you this info, which is before taxes

E-5 (Petty Officer Second Class), 3 years service, $2375.40/month
E-7 (Chief Petty Officer), 10 years service, $3611.70/month
E-9 (Master Chief Petty Officer), 20 years, $ 5523.60/month
O-1 (Ensign), 2 years , $2943.90/month
O-3 (Lieutenant), 4 years, $5031.00/month
O-4 (Lt. Commander), 10 years, $6418.50/month
O-6 (Captain), 24 years, $9866.70/month
These ranks and times are typical at that given point in a career. What YOU need to decide is what YOU want to do. Do you want to operate the plant? Enlisted is probably for you. Do you want to be in a leadership role? Then officer may be more what you want. If you want to be employed in an operating plant outside of the Navy, you'll need a technical degree or some time actually operating a plant or supervising others operating a plant in the Navy. The decision, however, is something only YOU can decide on. Nothing any of us say here is going to answer that question for you.
Planning out long term goals is easier for some than others. This is a HUGE step in your life, talk it over with family and important others in your life. Think about, pray about it, meditate about, whatever works for YOU.
Hopefully you caught on to the emphasis in this post. Also, don’t let money be the only deciding factor for you. As a nuke officer, you get opportunities to do other things in the Navy besides being a nuke. As an enlisted nuke, the only other viable option for you, that isn’t potentially career killing, is being a recruiter. Otherwise, your career rotation goes ship – training command – ship – training command, etc.
Again, best of luck to you.
