Maui and Kauai share Hawaii's state tax position but face materially different STR regulatory environments. Maui has active post-Lahaina STR phase-out plans; Kauai operates a more stable STR ordinance regime with less regulatory uncertainty. For STR-intent buyers, the inter-island regulatory difference is more important than the cost-seg study itself.
Across 5 engine fixtures for the Maui area, the differences between Kauai and the rest of Maui come down to three factors: land allocation, property archetype mix, and HOA capital-assessment patterns. See the per-fixture detail below.

It depends on what "better" means.
If you measure ROI as Year-1 federal savings dollars: Kauai wins on absolute dollars (higher purchase prices = larger absolute deductions). If you measure ROI as savings-per-dollar-of-purchase: the broader Maui non-resort sub-markets typically win (lower land allocation = more depreciable basis as % of price).
For most buyers, the more useful question is: which sub-market matches my buy-box? If you're already buying $2M+ resort-tier product, the cost-seg differential is a rounding error against your decision drivers. If you're price-shopping across sub-markets and considering both, the broader Maui non-resort areas produce more reclassification per dollar.
