Which is better for tight spaces?

The DEWALT DCF923B. Its ATOMIC compact body is built for confined areas, and it weighs 2.77 lbs. The Milwaukee's dimensions are not published, so the DEWALT is the safer pick when clearance is tight.

Is the Milwaukee worth the extra $70?

Only if top speed matters. The Milwaukee reaches 3,400 RPM and 3,600 IPM versus 2,800 RPM and 3,200 IPM for the DEWALT. For most 3/8 in jobs the DEWALT's 450 ft-lbs breakaway torque is enough.

Which has more torque?

The DEWALT publishes 450 ft-lbs breakaway and 300 ft-lbs fastening torque. Milwaukee does not publish torque for the 3049 in the given specs, so a direct comparison is not possible.

Does the DEWALT come with a battery?

No. The DCF923B is tool only, with zero batteries included. It runs on DEWALT 20V MAX lithium-ion packs, and a 3 Ah pack charges in about an hour.

Both use brushless motors, which outlast brushed designs. The DEWALT's brushless motor is confirmed in its specs; the Milwaukee's motor type is not published, so durability beyond that is hard to call.

Which is better for lug nuts?

The DEWALT's 450 ft-lbs breakaway torque handles most passenger-car lug nuts. The Milwaukee's torque is not published, so check its rating before relying on it for heavy lug nut work.
