The north has the most difficult sections of the trail with the least accessible sources of support. If you start in tge siuth there will be more people around you. The trails are not as steep or rocky. More trail angels more shuttle operators. Peole are generally happier ti see you and if needed help you out. 3000 people start in tge south only 900 from the north
Most people go South to North to get an earlier start. Mt Katahdin is not open in the early March and the weather in New England is pretty rough in March. If you start in the South, weather can still be bad in the Ozarks but spring is right around the corner.
