This article details a head-to-head comparison of two popular smokers: the Masterbuilt Gravity Series 560 and the Pit Boss 820 pellet grill. Both grills were used to smoke chuck roasts under identical conditions, allowing for a direct comparison of their performance and resulting quality of the cooked meat. The experiment meticulously documented the cooking process, from initial setup and temperature monitoring to the final blind taste test. This comprehensive review aims to assist potential buyers in making an informed decision by highlighting the strengths and weaknesses of each smoker.The showdown focused on achieving optimal tenderness and flavor in the chuck roasts. Factors like temperature consistency, ease of use, and the impact of different fuel sources (charcoal vs. pellets) were carefully considered. The results reveal key differences in cooking times, temperature stability, and ultimately, the final product’s palatability. This comparison offers valuable insights for both seasoned pitmasters and those new to the world of low-and-slow smoking.
Pros And Cons
- Smaller temperature swings (compared to Pit Boss)
- Chuck roast cooked faster than on the Pit Boss
- One example showed overcooking due to user error with temperature probe placement.

Setup and Preparation
The experiment involved two digital smokers: the Masterbuilt Gravity Series 560 electric charcoal smoker and the Pit Boss 820 pellet grill. Both were set to 250°F for cooking two chuck roasts.

For the Masterbuilt, El Diablo lump charcoal and mesquite wood chips were used. The Pit Boss used Trigger brand mesquite pellets.

Both chuck roasts received the same seasoning: a generous coating of Nilsa Wraps Tasty Seer Gourmet beef rub, using extra virgin olive oil as a binder. No additional spritzing or adjustments were made during cooking.

The Cooking Process
The chuck roasts were placed on their respective grills at approximately 11:00 AM. The Pit Boss showed slightly larger temperature swings than the Masterbuilt throughout the cooking process.

The cooking process was largely hands-off; no spritzing or adjustments were made. The internal temperature of each chuck roast was monitored periodically.

The roasts were considered done around 200°F internal temperature, confirmed with a tender poke test, then rested in foil for 30-60 minutes before slicing.
Results and Taste Test
The Masterbuilt chuck roast reached 200°F first and passed the tender test. However, the Pit Boss chuck roast took 30 minutes longer and reached 198°F.

A blind taste test was conducted with family members. The Masterbuilt chuck roast was slightly overcooked, resulting in a dry texture, though the flavor was still good.

The Pit Boss chuck roast was judged to be more tender and juicy, resulting in a preferable taste and texture.
Conclusion and Recommendations
While the Pit Boss pellet grill ultimately produced the more tender and flavorful chuck roast, the Masterbuilt Gravity Series 560 did well, except for the overcooking issue. The overcooking was more a result of user error than a flaw in the grill itself.
The Pit Boss 820 showed some temperature inconsistencies but ultimately provided a superior result this time. The Masterbuilt was easier to use initially but required more attention to temperature monitoring.
Both grills offer different features and benefits. The Masterbuilt’s charcoal provides a unique flavor, and the Pit Boss offers more even temperature control and convenience with wood pellets. Your choice depends on your preferred cooking style and the level of hands-on attention you're willing to give.
