Personally I have found the sideslip method the easiest for low time pilots. While the kick out the crab seems easy, in practice timing the kick out is hard for low time pilots as it occurs at the time of maximum work load in the landing flare so that they are either too late which means the aircraft is crooked when it touches down or too early which means the aircraft will touch down with significant sideways drift.
I tell students to hold a crab until about 300 feet above ground on final and then align the aircraft with the runway centerline and adjust the lateral displacement ( ie whether you are left or right of the runway centerline) with bank. If the airplane is drifting downwind add more bank if the aircraft is moving upwind reduce the bank.
Don't worry about coordination. Do what ever it takes with the rudder to keep the airplane pointed straight down the runway but deliberately adjust the bank to attain/maintain the aircraft position over the middle of the runway.
