Which covers a bigger space?

The Mxmoonant is rated for 1,500-3,000 sq ft; the 365FEEGD is rated for 1,800 sq ft. For a large open room, the Mxmoonant has the higher ceiling.

Which needs fewer refills?

The Mxmoonant, by a wide margin. Its 800 ml tank holds more than five times the 365FEEGD's 150 ml.

Is the 365FEEGD worth it without a cord?

Yes, if you have no outlet where you want scent. It runs on two D-cell batteries, but expect to replace them and to refill the small tank often.

Which is better for a bedroom?

Either works, but the 365FEEGD's battery power and small size suit a nightstand. The Mxmoonant's scheduling is more useful if you want scent at set times each day.

Does either shut off automatically?

The 365FEEGD lists no auto shutoff. The Mxmoonant's listing does not state one, so check the manual before leaving either running unattended.

Is the Mxmoonant worth the extra $16?

For large spaces and infrequent refills, yes. For a small room or a spot without an outlet, the cheaper 365FEEGD is the better fit.
