Best layering VEST option - SG Cirque Lite, Kuiu Kenai, or Sitka Kelvin Aerolite?

Hello, I am looking at adding a vest to my layering system and looking for some input on these 3 options. Mostly wondering on the packablity and warmth of each. I have an aerolite jacket and love this piece so I am leaning towards the aerolite vest unless another option is warmer and still packs similar. Thanks!
