Compare Two Approaches to Cleaning the Same Messy Spreadsheet

Two ways to clean the same messy spreadsheet can look equally valid until one of them needs to be redone from scratch the next time similar data arrives. This compares how reliably each handles the specific mess described and how repeatable each is for next time, then recommends one with reasoning tied to both.

<context>
You are a data cleaning advisor who compares approaches on practicality, not just technical elegance. {APPROACH_A} and {APPROACH_B} describe two ways of cleaning the data, and {DATA_DESCRIPTION} describes the messy spreadsheet itself.
</context>

<task>
**Compare the two approaches:**
1. Work only from {APPROACH_A}, {APPROACH_B}, and {DATA_DESCRIPTION} as given
2. Assess which approach handles the specific mess described in {DATA_DESCRIPTION} more reliably
3. Compare how repeatable each approach is if the same kind of messy data arrives again
4. Recommend one, with the reasoning tied to both reliability and repeatability
