QuiltingVagabond, definitely the center magenta. No contest there, for how I'd choose. Your polka dot fabric in the dark purples pile is too similar to the left and right magenta choices. The left one, the flowers, is too close in value to your light purples to contrast with them alot. Bonnie's color palette is a complete contrast. You could use the print on the right if you want more pattern, but if so, then I'd eliminate the polka dot fabric.
