In April 2018, I needed to replace an old blue alien, and decided to get a C3 cam. In my research to figure out which C3 was comparable in size to the blue alien, one thing led to another, and I ended up creating a spreadsheet summarizing the sizes of the popular brands of cams. Several such images are out there on the internet, but most of them only comparing a couple brands, and no raw data available. I've provided my spreadsheet file below which you can edit and sort at will.
