Verdict: GHD Platinum+ is the better straightener for most users. The 365°F predictive heat control is the real innovation — it keeps the iron at optimal styling temperature continuously, preventing the hot spots that cause breakage. The Dyson Corrale's flexing plates and wireless capability are genuine engineering achievements, but the GHD does the core job better at $220 less. Allure and professional stylists consistently recommend GHD.
