Don't know much about the modern status of things... but traveling in the way back machine there were different rules for different rulers, whether you cut on the lines or next to the lines. It can make a difference, but also your seam size probably makes more of a difference. When I first started quilting I started being very precise, as the decades have passed I'm happier with my cut large and trim down and I get better results. With my vision issues, many of the rulers are just too busy for me with the lines and hatch marks and colors and clear or cloudy and all the other innovations that are put in to make themselves different from each other. Seriously, I can't see the 1/8th marks much less 1/16, so I typically only use 1/4" increments. Don't care if the math (along with perfect seam allowances) for a triangle is +7/8ths to the measurement. 1" barely wastes any fabric and does give enough for either forgiveness or worthwhile trimming off.
Unlike you -- I do like the quilters rule for the grip on my long cuts! I know there are other options now from weights to sandpaper dots, but non-slip is my way to go! I also think how you cut with the quilters rule makes a difference. I typically use the two rulers technique where i establish my depth of cut with one ruler and then line up the Quilters Rule for the long cut. To help with my vision and accuracy (and a bit of anti-slip) if I'm cutting a lot of strips, I will mark the measurement with tape so I don't have to focus in on those little hatches.
