Member's Mark 4-Burner 36" Griddle: Sold at both 48,000 BTU and 60,000 BTU with the same 720 sq in surface. Read the BTU figure off the box.
Check the BTU label first
Before anything else: Member’s Mark sells 720-square-inch four-burner griddles at both 48,000 and 60,000 BTU. That is 66.7 versus 83.3 BTU per square inch — a 25% difference in available heat between two griddles that look identical in a listing.
The 60,000 BTU version beats the Blackstone 36’s 78.0 BTU per square inch. The 48,000 BTU version is well behind it. You cannot sensibly run this comparison without knowing which one is in front of you.
The table above uses the 48,000 BTU figure, which is the more conservative assumption.
Where Member’s Mark is genuinely good
304 stainless burners are a better grade than several considerably more expensive griddles use. Burners are the consumable on any gas appliance — they corrode from the inside out over years — so burner grade is one of the few spec-sheet details that genuinely predicts how long the griddle lasts.
All-weather electronic ignition is the other sensible choice. Ignition is usually the first thing to annoy you on a griddle, and an all-weather electronic system outlasts a basic piezo button.
Both are exactly the right places to have spent money, and it is a more considered build than the price positioning suggests.
Where Blackstone wins, and it is not cooking
Surface area is close — 769 against 720, under 7%, which is noise at this size.
The real gap is support. Blackstone’s parts and accessory availability at 36 inches is the best in the category: covers, hoods, replacement cooktops, burner assemblies and regulators, from the manufacturer and a large third-party market.
Member’s Mark is a club-store exclusive. Warranty service runs through that channel, replacement parts are harder to source, and third-party accessory support — including finding a correctly-sized cover — is thin.
None of that matters in year one. All of it matters in year four, which is when a griddle gets repaired or replaced.
Which to buy
Member’s Mark if you are a member, you have verified the BTU rating on the box, and you accept thinner long-term parts support. On the 60,000 BTU version particularly, the specs are strong and the value is real.
Blackstone 36 if you want certainty that you can buy any part for the next decade. Treat the difference as insurance rather than brand tax — which is the same argument as Blackstone against Nexgrill.
The picks in detail

Blackstone 36" Original Griddle
The default large griddle: four burners over 769 square inches, with the highest burner count in its size class and the deepest accessory ecosystem of any brand here.

Scores
- Cooking area9.5
- Heat output9.0
- Zone control9.5
- Surface care6.5
- Portability3.0
What works
- Four independent zones is the real argument for this size — you can hold a warm zone and still sear
- 769 sq in is enough to cook a full breakfast for eight without staging
- The widest accessory and spare-parts availability of any brand in this guide
What to know
- Bare carbon steel: it will rust if you leave it uncovered and unseasoned
- Needs real patio footprint — this is not a griddle you put away each week
- Rear grease management means the drain is behind the unit, which is awkward against a wall
#2 · Club-store buyers
Member's Mark 4-Burner 36" Griddle
720 square inches with 304 stainless burners — a credible large griddle, sold in two BTU ratings that are easy to confuse.
