Flavor & Heat Distribution
Both use Flav-R-Wave™ stainless system. Dual-Tube burners ensure consistent flame coverage. Regal’s higher BTU density enhances searing performance.
Ignition & Smart Features
Baron 590: Sure-Lite single-electrode electronic ignition. Regal S590 Pro: Sure-Lite dual-electrode, optional iQue™ smart-grilling variant with digital temperature control (2025 update).

Warranty & Longevity
Baron: Limited lifetime on cook box, 15 years on burners and parts. Regal: Limited lifetime on cook box, 10+ years on burners and parts. Proper cleaning, covering, and maintenance extend lifespan.
User Feedback & Considerations
- Regal’s heavier 9 mm grids improve searing and heat retention.
