The short answer: Buy Blackstone if you want long-term support, a massive accessory ecosystem, and proven resale value. Buy Members Mark if you’re a Sam’s Club member who wants solid griddle performance at 20–30% less cost and aren’t concerned about long-term parts availability.
Both cook well. The difference is the ownership experience, not the cooking performance.
I’ve owned both — a Members Mark 4-burner and multiple Blackstone models (17″, 22″, and 36″) — over 5+ years. This comparison comes from hundreds of hours of actual cooking, not spec sheets.

BTU and Heat Performance: What the Numbers Actually Mean
The Members Mark runs ~40,000 BTU across 4 burners. The Blackstone 36″ runs 60,000 BTU across 4 burners. On paper, that’s a significant gap — 50% more heat output for Blackstone.
In practice, the cooking surface temperature difference is real but less dramatic than the BTU gap suggests. Both griddles reach temperatures adequate for searing, cooking eggs, and making smash burgers. The Members Mark takes longer to preheat (8–10 minutes vs 5–7 for Blackstone) and struggles more on cold days when outdoor temperatures drop below 50°F.
For everyday cooking, the Members Mark’s heat output is sufficient. If you cook in cold climates regularly or prioritize getting to searing temperature fast, Blackstone’s higher BTU is a meaningful advantage.
Build Quality and Materials
Both griddles use a carbon steel cooking surface (not cast iron, not stainless). The steel gauges are similar. Neither griddle will rust if properly seasoned and covered — both will rust quickly if left uncovered and unseasoned.
The frame construction on Blackstone is slightly more refined, with better powder-coat consistency and tighter tolerances on folding legs and side tables. The Members Mark frame is functional but shows more variation in finish quality unit-to-unit.
Day-to-day cooking durability: comparable. Long-term durability advantage: Blackstone, primarily because replacement parts are available when something eventually fails.
The Accessory and Parts Ecosystem — Where Blackstone Wins Decisively
This is the most important practical difference and the one most people underestimate before buying.
Blackstone has built a comprehensive accessory ecosystem: press attachments, air fryer add-ons, pizza oven attachments, griddle covers, carry bags, spatula sets, grease cups, and replacement parts (regulators, igniters, burner valves, griddle tops). Everything is available on Amazon, at Walmart, and on Blackstone’s own website.
Members Mark accessories are limited to covers and basic spatula sets. When something breaks — and after a few years of use, something will — you’re looking at Sam’s Club directly, which may or may not carry the part, or generic replacements that may or may not fit.
A failed regulator on a Blackstone is a $20 fix you can order today. A failed regulator on a Members Mark may require calling Sam’s Club customer service and waiting on a part that’s not universally stocked.
Who Should Buy Members Mark
- You’re a Sam’s Club member and the lower price is a real factor
- You want a capable griddle for casual weekend use
- You’re not planning on using accessories or specialty attachments
- You’re comfortable buying a replacement unit rather than repairing it if something fails
Who Should Buy Blackstone
- You want the most supported griddle in the market
- You plan to use accessories (press, cover, carry bags)
- You cook in cold weather or want max heat output
- You want active community support (Reddit, YouTube tutorials, Facebook groups)
- Long-term repair and maintenance matter to you
Frequently Asked Questions
Is Members Mark the same as Blackstone?
No. Members Mark griddles are made by a different manufacturer and sold exclusively through Sam’s Club. Similar form factor, different components, separate parts ecosystem.
Can I use Blackstone accessories on a Members Mark griddle?
Generic accessories (spatulas, covers sized by inch) are usually cross-compatible. Model-specific accessories like Blackstone’s air fryer attachment or press attachment are not compatible with Members Mark.
Is the Members Mark griddle a good deal?
Yes, if price is your primary factor and you’re a Sam’s Club member. You get a functional 4-burner griddle at a solid discount. The trade-off is limited parts availability and a much smaller support community.
Which griddle is better for a beginner?
Blackstone — because of the larger community, more tutorials, and easier access to parts if something goes wrong while you’re learning.
Does the Members Mark griddle rust?
Like all carbon steel cooking surfaces, yes if left uncovered and unseasoned. Rust behavior is similar to Blackstone. The bigger risk with Members Mark is that replacement griddle tops are hard to source if rust becomes severe.
What’s the price difference between Members Mark and Blackstone?
Members Mark typically runs $350–400. Blackstone 36″ typically runs $400–500, with frequent sales bringing it to $350–380. On sale, the price difference is minimal — which changes the calculus toward Blackstone significantly.
