Best relative seniority. Stay in NYC and there is a lot of opportunity for good trips, pay and time off. As a day-1 new hire I thought I'd prefer reserve in ATL over a line in NYC. Now that I've had a taste of commuting to both reserve and holding a line that no longer holds true. Now, if it was sit at home on my couch for reserve vs. commuting to a line my tune might change but if you have to commute, a line is umpteen zillion times better.
