Y'know, I've tried all three methods (paper piecing, strip and cut-to-fit), all of them work, but each works best depending on what I am doing. If all the darks are the same and all the lights are the same, and it's a large block (12" finished or larger) I use the strip method. If it's Scrap City and the blocks are 9" or larger, I cut to fit. For every other size (i.e., smaller), whether or not darks/lights are the same, I paper piece.
