I've tried both on AB, B, and MD aircraft and have found the only consistent method for me is steady increase in angle of attack. However, the flare altitude has to be correct or you will float, especially when light, hot, or high pressure altitude airports due to higher than normal tas. To make consistent good landings start well before the flare point by having stabilized approaches paying particular attention to maintaining a constant pitch attitude. Futhermore, a professional knows a greaser is more luck than anything else and prides himself on how well the approach was flown, on gs, on speed, on centerline, in the tdze, with correct xwind application, full reverse if practable as soon as main wheel touchdown, otherwise you're just making noise.
