>>1465214Unless fit is an issue, I would choose Atom.
I have an Atom LT and a Micropuff. They are both awesome but the Atom is just a little bit better on a lot of small details (like pocket size/placement, zippers, cuffs, etc).
I bought the Atom on sale and liked it so much I bought immediately bought a second one.
I still use the Micropuff regularly, but only because the Atom LT is a fair bit lighter than the Micropuff so they serve somewhat different purposes for me.
