IMO easiest to fly, which is the OP's question are the Piper PA-28 series aircraft and the Cessna 152 and 172. There is a reason why many flight schools use them. For tail draggers, the Cub is the choice of champions. These are all great choices for very low time pilots. While I agree that there are other aircraft that may be "easy-ish" to fly like the Bonanza, things happen too quickly for a low time pilot. You need to get your brain trained to be comfortable at speed before you upgrade to higher performance aircraft. I am sure there are some light sport category planes that would fit the easy to fly category.

I completely agree with the comments regarding judgement and that is a whole 'nother can of worms. I used to read Aviation Safety regularly and nearly all of the reported accidents could be attributed to poor judgment. Flying a poorly (or incorrectly) maintained aircraft, improper preflight, pushing the fuel limits, pushing the performance limits, pushing the pilot's limits, flight into IMC by a VFR pilot, flight into known icing conditions without deice equipment.
