I prefer the Olfa, they have a little frosting on them which helps me see better. Fav ruler - 6x12, 3x18 12.5x12.5 in that order. the sqaures - 6.5x6.5, 9.5x9.5 in that order. I like the 1/8th inch increments best, the yellow lines the very least, as they even seem to give me a headache - too much eye for the to handle. The Fiskers 6x24 is tricky - one side has a half inch unmarked edge. Ruined lots of fabric with that. Templates - Hexagon, then diamond.
