Memories is nice, but it's not superwash and it's really thick for a fingering weight yarn.
Essential is a good, sturdy, workhorse sock yarn. It's a good one to use for socks that will get a lot of wear.
Palette is really rough. I couldn't stand to even touch it, it's MUCH rougher than WOTA.
Gloss is fantastic. The silk content adds strength and a beautiful sheen to the yarn.This yarn is REALLY soft.
