Having the nose wheel on the ground on a tricycle undercarriage aircraft improves control as it is forward of the CofG and allows the pilot to have a better view along the runway. On the A320 forward side stick is recommended below 100kts on take off to aid in maintaining direction.
With a tail wheel aircraft, the rear wheel is behind the CofG and often assists the rear end in trying to overtake the front end, similar to a lorry jackknifing. Many a tail dragger pilot has enjoyed a 360’ panoramic view of the airport during a misjudged landing and subsequent ground loop. On take off, the idea was to get the tail up, improve the forward view and steer aerodynamically using the rudder. Landing had two schools of thought, one was to three point the aircraft which generally resulted in a shorter ground run, the other was to land on the main wheels first and lower the tail as the speed decayed.
