"Fail to see the benefit of wheelers..."
One benefit is that you don't come close to the stall during the roundout. No issue there, then, unless you get to fly something like the DH Dragon Rapide. This aeroplane (and others) is apparently prone to tip stalling - VERY pronounced wing drop at the stall. This is fine as long as you arrive in the correct three point attitude at the correct height above the runway EVERY TIME! For the rest of us mere mortals, a much safer approach is to get the main wheels down at a much safer (faster ) speed and let the speed decay whilst on the runway. More rudder control during the rollout and less danger of a ONE(wingtip) point landing!
This is not my own opinion/experience, by the way (I've never flown this aeroplane), but that of a very experienced friend who advocates the tail down wheeler every time in such a/c.
I believe this is also the case with the DC3!
