Which is warmer for fall hiking?

The REI Co-op 650 Down Jacket states 650-fill down and a windproof, water-resistant shell, so it is the safer pick for cold, windy hikes. The Uniqlo does not state its fill power, so its warmth is less predictable.

The Uniqlo Ultra Light Down Jacket comes with a carrying pouch and is built to pack down small. The REI jacket has no listed stuff sack and its roomy cut takes more space.

Is the Uniqlo worth the extra $6.17?

Only if packability and the anti-static lining matter to you. Otherwise the REI is cheaper at $63.83 and states its 650-fill down.

Which fits larger bodies better?

The REI goes up to 3X, including 1X and 2X, with a relaxed cut. The Uniqlo tops out at XXL with a slimmer fit.

Do either have a hood?

No. Both the REI Co-op 650 Down Jacket and the Uniqlo Ultra Light Down Jacket are hoodless, so add a hat or a shell with a hood in wind.

Which holds up better in rain?

Neither is waterproof. The REI uses a water-resistant recycled ripstop nylon shell; the Uniqlo uses Toray NANODESIGN water-repellent fabric. Both shed light drizzle, not steady rain.
