Thanks for that tip Mac. I don't have DC-3 time and haven't read the flight limitations, yet. Reading up more it seem that there are airplanes that are far easier to wheel land than to three-point, such as the Globe/Temco Swift, the Beech 18 and DC-3.
The J-3, C-170, definitely did numerous 3-point and main wheel landings. If a pilot is not current, or does not have a lot of tailwheel time, and if there is not a strong or gusty crosswind (each individual pilot has to define strong), a three-point landing is usually the better way to go. There is less kinetic energy to deal with during the rollout, and flaring at the wrong height or making a hard landing is no big deal, so the pilot can concentrate on just one variable, directional control. It is the more conservative landing in most airplanes, and when in doubt, the conservative approach to dealing with a moving object is often the better one.
I consider myself one of the lucky ones, no ground loop... yet?
Here what the US FAA has to say about tailwheel transition per Airplane Flying Handbook (FAA-H-8083-3C),
