I get a little bored with the sigma rubi banter to be honest i have both brands and use what ever works well for the materials i am using ,the ts 40 is the best cutter bar none for ceramic wall tiling ,the sigma 3ek/em is the best machine on the market for large format porcelain in my opinion so it boils down to what type of work you do and what you are comfortable using
