Variant 1

White will have to work that little bit harder to obtain a smoother distribution. Initially and as a consequence, she'll need to play a little inefficiently which may cost her in the long run. With no opposing checkers to contain the bar and 8pt share an important responsibility. In general, checkers on these points are inefficient and should be the last to vacate the outfield. If they are used too soon then checkers remaining further in the outfield (especially the mid point) will either clear two quadrants or reluctantly reoccupy them and compound the inefficiency.

Variant 2

Its significantly easier for White to play with optimum efficiency when she already has a smoother distribution. Conversely, Blue has a little less freedom to play with optimum efficiency.
