"Don't kill me...it's a real question".
That cracked me up.
Some of the big bloggers, yes, are being sponsored , so you are right in assuming an apparent bias. That being said,
I have bought Aurifil and preferred it over CT or C&C, but for the price it's not my go-to piecing thread. CT thread is
what my daughter bought me in 12 colors of the rainbow, so I use it for piecing and probably will "till the cows come home" since it's there.
It's a bit lintier, but I enjoy cleaning out lint (I know I'm weird--I enjoy cleaning out the lint trap every load from the dryer, too, and using a lint roller on clothes.)
I'd say if it's working for you, why change? But do give yourself permission to try a spool of Aurifil, Superior, or Glide and see if it makes a noticeable enough difference for you to spend more. Go medium grey so you get the versatility of piecing and quilting most things without worrying about color clashing.
