I used C&C for years, never was a thread snob, someone gave me some beautiful varigated Wonderfil and I loved it, used that for a few years and then someone gifted me some Aurifil...and I used up all my other brands and never looked back, it works so well in all my machines! I gifted some to my mom for Mother's Day one year and that's all she uses now as well, never thought I would be a thread snob LOL
