Both grills are aimed at the same buyer: someone who wants serious charcoal cooking and is willing to spend $1,500-$2,000 to get the best version. The Weber Summit Charcoal is a high-end Kettle on steroids. The Kamado Joe Classic III is the modern kamado king. Different shapes, different philosophies.
Quick Verdict
Buy the Weber Summit Charcoal ($1,799) if you want a high-end traditional charcoal grill with a hinged lid and Weber's familiar layout. Buy the Kamado Joe Classic III ($2,099) if you want the most efficient, multi-purpose ceramic cooker on the market.

Versatility
Winner: Kamado JoeKamado Joe wins. The Divide & Conquer system lets you cook multiple foods at multiple temps simultaneously. Pizza, low-and-slow brisket, hot-and-fast steak — all done well. The Summit is excellent at grilling and good at smoking but lacks that multi-zone flexibility.
Fuel Efficiency
Winner: Kamado JoeKamado Joe wins. The ceramic body is dramatically more efficient — 18+ hour cooks on 5-6 lbs of charcoal. The Summit is insulated but still uses 2-3x more charcoal for the same low-and-slow cook.
Ease of Use
Winner: SummitSummit wins. Weber's familiar layout, hinged lid, and big work surfaces make it more intuitive for someone coming from a Kettle. Kamados have a learning curve — vent management, no peeking, and the temp recovery is slow if you over-correct.
Searing & High Heat
Winner: TieTie. Both hit 700°F+ easily. The Summit's wide-open round grate makes managing multiple steaks easier; the Kamado Joe sears hotter at the dome but has less surface area for direct grilling.
Long-Term Durability
Winner: Kamado JoeKamado Joe wins. The ceramic body will outlast the steel Summit. Both have lifetime warranties on key components, but barring a drop, a Kamado lasts forever.
Final Verdict
Buy the Weber Summit Charcoal if you love your Weber Kettle and want a premium upgrade that feels familiar. Buy the Kamado Joe Classic III if you want the most versatile, efficient charcoal cooker money can buy at this price.
Buying Advice
If you've never owned a kamado, it's worth visiting a dealer to see if the workflow appeals to you — kamados require a different mindset than Weber-style grills. If the kamado vibe doesn't click, the Summit is the better grill for you.
