Hevily depends on the type of aircraft. Short range aircraft have their take of of weight close to the landing weight and get beaten several flights a day. Long range aircraft may do just one flight per day, but they taxi out significantly more heavy than they land. Fast turns on taxi out may indeed produce the highest sideloads. Depending on the design of the gear again, this may create the highest stress in the most critical locations, while the stress distributes much more evenly on a straight landing.
