I use Aurifil almost exclusively. So much less lint than other cotton threads. Several years ago, there was a store I was getting it from that was discontinuing it, so I bought quite a bit. Some are not your typical neutrals - kind of peach color - but they work well and rarely do you see thread anyhow.
A couple of years ago, I found Wawak, and got some specific Aurifil colors I needed, they have great service and pricing. But during Covid, they stopped carrying it, too.
If I need any now, I look online for sales of cones. Much better deal if you can figure a way to rig it at your sewing station.
