My understanding re: Army aviation is that line (?) officers almost always have less flight time than an equivalent CWO.
"Almost always" = "Yup"
WO:
Pros: More flight time. You will stay in the company until mid to senior CW3, which means most of your career will be spent flying and being involved in the daily operations of a flight company. Your job and reputation revolve around being a professional aviator.
Cons: Less pay. Less responsibility. You will be the guy who has to follow the orders, even if they're dumb or counterproductive. You will have dumb additional duties to do, and some important ones depending on what you track.
LO:
Pros: You can still fly quite a bit up until the point you make CPT. You make a lot more money. You get to make decisions and lead/command. Some people care about that more than others, but it's nice to be able to set the policies and work flow of an organization for the better.
Cons: After the mid-senior CPT point, your job becomes about being a staff officer and planner, not a pilot. You will be expected by your leadership to do officer stuff first and being a pilot will be anywhere from second to fifth+ on the priority list. You will have a ton of paperwork to do. You have a high chance of being put in a non-flying assignment or billet.
