Main trade-off
Pit Boss 500FB2 Wood Pellet Grill
The 5-pound hopper needs attention on long cooks and does not justify an all-night refill claim.
Head-to-head
Pit Boss 500FB2 vs Z Grills 550B: Pit Boss sears over direct flame, Z GRILLS adds lower-rack and pellet room
The short answer
Choose direct-flame access or the larger published lower rack and hopper.
Before you choose
The reasoning and the trade-offs
Compare total multi-level rack area on the same basis
500FB2 provides 518 square inches and 550B provides 560. The absolute difference is 42 square inches, or 8.1% of the smaller figure.
What this is based on
560 minus 518 = 42 sq in. 42 ÷ 518 × 100 = 8.1%. Both values include multiple rack levels, so this is not contiguous pan area. No serving count is inferred.
Main trade-off
Z GRILLS ZPG-550B Pellet Grill
The 10-pound hopper is marginal for a conservative 12-hour no-refill plan.

Winner by situation
Start with what you need it to do
A meal that needs the largest uninterrupted main grate
The total rack areas are relatively close at 518 and 560 square inches. Z Grills publishes 406 square inches on its lower rack, which helps evaluate food that cannot fit under the upper shelf.

A long cook with a planned pellet reserve
The checked 550B specification table lists an 8lb hopper, although its introductory copy also mentions 10lb. This comparison uses the smaller explicit table value and flags the conflict for confirmation before purchase.

Repeated cooks where cleanup and movement matter

What matters in practice
The differences that matter
Compare total multi-level rack area on the same basis
500FB2 provides 518 square inches and 550B provides 560. The absolute difference is 42 square inches, or 8.1% of the smaller figure.
How we reached this conclusion
560 minus 518 = 42 sq in. 42 ÷ 518 × 100 = 8.1%. Both values include multiple rack levels, so this is not contiguous pan area. No serving count is inferred.
A stated pellet-burn assumption makes the hopper comparison usable
At an illustrative 1.5lb per hour, a full 5lb hopper represents 3.3 hours of fuel and a 8lb hopper represents 5.3 hours. These are planning estimates before any reserve.
How we reached this conclusion
Assume the same constant 1.5lb/h consumption solely to normalize hopper size. 5 ÷ 1.5 = 3.3h. 8 ÷ 1.5 = 5.3h. Actual use varies with temperature, weather, food and grill design. This is not an unattended-use recommendation.
A 475°F recipe sits between their controller limits
Pit Boss has 25°F of setting headroom above 475°F. Z Grills is 25°F below that requested setting.
How we reached this conclusion
500 minus 475 = 25°F. 450 minus 475 = negative 25°F. This does not measure actual grate heat or browning performance.
