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

Weber Slate 30

  • Rust-resistant hardened cooktop genuinely reduces upkeep vs bare rolled steel
  • Very even heat across all 540 sq in - fewer hot/cold zones than Blackstone
  • 36,000 BTU across 3 burners preheats fast and holds sear temps over 500F
  • Front-corner grease trap is simple and mess-free
  • Heavy, rigid cart with side tables, wind guards, and locking casters
  • 5-year warranty is the best in the griddle category
  • Twice the price of a similar-size Blackstone
  • Base 1500014 trim lacks the premium model's digital temp display
  • Cooktop rust is excluded from the warranty despite the rust-resistant pitch
  • Weber Works accessories add up quickly
  • Still requires seasoning and oiling like any carbon-steel griddle
