Pros & cons
Weber Slate 36
- ✓The case-hardened, pre-seasoned carbon steel cooktop genuinely resists the rust that plagues Blackstone owners who leave their griddle outside
- ✓Four independently controlled burners give real multi-zone cooking - pancakes on low while smash burgers sear on high
- ✓The built-in digital cooktop thermometer takes the guesswork out of surface temp, something no Blackstone offers stock
- ✓48,000 BTUs heat the 756 sq in surface past 500°F quickly and evenly, with fewer cold corners than budget griddles
- ✓Weber's fit and finish is a clear step up - solid hinges, smooth-rolling casters, and an enclosed cart that keeps propane and tools out of the weather
- ✓The grease management system funnels into an easy-access catch pan instead of the messy rear-drip setups on cheaper flat tops
- ✓Flip-up side table and tool hooks add workspace without widening the footprint much
- ✓Backed by Weber's warranty and dealer network, so parts and service are far easier to get than for import-brand griddles
- ✗At $999 it costs roughly double a comparable 36-inch Blackstone, which is a hard sell for occasional griddlers
- ✗The digital thermometer reads one spot on the cooktop and can disagree with an IR gun by 30-50°F across zones
- ✗The cooktop is rust-resistant, not rust-proof - neglect the seasoning or leave it uncovered and it will still spot
- ✗No lid-down convection cooking - like all flat tops it's a one-trick pony compared to a grill/griddle combo
- ✗Assembly involves many cart panels and screws, commonly taking 1.5-2 hours
- ✗It's heavy (about 150 lbs) and wide with the side table up, so it needs real patio space
- ✗Propane-only out of the box - natural gas requires buying a different SKU, not a conversion kit
- ✗No WiFi or app connectivity even at this premium price, while Weber's own gas grills get Weber Connect
Traeger Flatrock 3 Zone Griddle
- ✓Physically insulated zone dividers hold a real temperature difference across the plate, not just a gradient
- ✓Five-year warranty against Blackstone's one, on a griddle at a comparable-to-premium price
- ✓FlameLock wind blocking addresses the most common cause of a griddle failing to hold heat
- ✓Published 350–600°F range, where most griddle makers publish nothing at all
- ✓Pop-and-Lock accessory rail shares Traeger's existing accessory ecosystem
- ✗$999 for 594 sq in, against 768 sq in on a $549 Blackstone Iron Forged 36
- ✗189 lbs is the heaviest griddle in this class by a wide margin
- ✗350°F low end is high — it will not hold food at a gentle warm the way a four-zone griddle set to minimum can
- ✗Cold-rolled steel plate, so the rust maintenance is the same as any Blackstone despite the price
- ✗No hood in the base configuration, which limits melting and steaming
