Short answer: both are discontinued, so this only matters if you are buying used. Used, the IK Multimedia iLoud MTM is the better pick: it ranks #30 of 100 powered bookshelf speakers by sound quality (rated 4.1/5), against #93 (rated 2.8/5) for the JBL One Series 104. If you want one new, the IK Multimedia iLoud MTM MKII replaces the IK Multimedia iLoud MTM and is rated 4.2/5 at $699.99.
The IK Multimedia iLoud MTM is the better-sounding choice. ASR’s measurements of the original MTM give scores of 4.07 standalone and 6.26 with an ideal subwoofer, a 2.4dB midrange response span and a -3dB point around 53Hz. Watch for: The MTM arrangement makes listening height and orientation important, while bass below the low-50Hz region still needs support.
The JBL One Series 104 is the deeper-bass choice. ASR’s powered-system measurement gives -3dB bass around 72Hz, and the compact coaxial layout is convenient for a small desk. Its bass reaches about 45Hz before falling 3dB, against 50Hz for the IK Multimedia iLoud MTM. It keeps a wired aux input, which the IK Multimedia iLoud MTM lacks. The tradeoff: Even with the active system measured properly, scores are only 1.36 standalone and 4.08 with an ideal subwoofer.
Buy the IK Multimedia iLoud MTM only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the IK Multimedia iLoud MTM MKII, which replaces the IK Multimedia iLoud MTM.

IK Multimedia iLoud MTM: $1,600 per pair Discontinued Amazon eBay
Newer model: the IK Multimedia iLoud MTM MKII, ranked higher, rated 4.2/5.
Pros: ASR’s measurements of the original MTM give scores of 4.07 standalone and 6.26 with an ideal subwoofer, a 2.4dB midrange response span and a -3dB point around 53Hz. The small cabinet, balanced input and calibration capability make it useful for close listening where larger monitors would be impractical. Measured bass extension of 50Hz (-3dB).
Cons: The MTM arrangement makes listening height and orientation important, while bass below the low-50Hz region still needs support. The native response is not as smooth as the best compact reference monitors. Exact compression ceilings and correction examples from the MKII review should not be assigned to this original version; its score describes tonal response, not maximum clean volume. Treble runs about 3dB hot on-axis; the reviewer found the rear -3dB switch too aggressive and preferred about -1.5dB of external EQ. Discontinued.

JBL One Series 104: $129 per pair Discontinued eBay
Pros: ASR’s powered-system measurement gives -3dB bass around 72Hz, and the compact coaxial layout is convenient for a small desk. Its internal equalization is part of the working speaker and should be included when assessing it, rather than judging the passive drivers with that correction bypassed. Measured bass extension of 45Hz (-3dB).
Cons: Even with the active system measured properly, scores are only 1.36 standalone and 4.08 with an ideal subwoofer. The 4.9dB midrange span and a high-frequency cancellation around 7.4kHz indicate significant unevenness; the review also found some vocals bright and irritating. These are results for the original 104, not a verification of the later 104-BT. Discontinued.
