* 모건 (Mogan): This is a common and straightforward transliteration, using the closest sounding Hangul syllables. It's likely the most easily understood option.
* 모르간 (Moreugan): This option attempts to capture a more "full" sound, potentially closer to certain pronunciations of the name.
The best choice depends on personal preference and how you want the name to sound in Korean. 모건 (Mogan) is generally the safest and most widely accepted option.
