gtmetrix.in Engineering Verdict
WordPress with WooCommerce wins for pure speed potential: with proper server-level caching and LiteSpeed/Redis, it consistently achieves 90+ mobile scores. Shopify offers zero-maintenance stability, but heavy app ecosystems often drag mobile scores down into the 40-60 range.
