 - Soli makes things simpler by giving each Hangul character a single, consistent Latin spelling. In contrast, RR and MR sometimes transcribe Hangul into multiple spellings due to different ways of pronouncing it in Korean.

 - Soli gives Hangul consonants a consistent Latin representation. In contrast, RR and MR use different Latin letters for Hangul consonants depending on whether they're at the beginning or end of a word. For example, ㄱ, ㄷ, ㄹ, and ㅂ are transcribed as g, d, r, b at the start, and k, t, l, p at the end.
 - Soli simplifies things by using the same Latin spelling for similar vowels: ㅜ/ㅡ become u, ㅐ/ㅔ become e, ㅒ/ㅖ become ye, ㅙ/ㅚ/ㅞ become oe, and ᅱ/ᅴ become ui. In contrast, RR adds 'a' or 'e' to certain vowels: ㅡ becomes eu, ㅐ becomes ae, and ᅫ becomes wae. This can be confusing and cause people to misread ㅡ as eh-u and ㅐ as ah-eh.
