The short answer

All-American 921 Cast Aluminum Pressure Canner (21.5-Quart) comes out ahead by a narrow margin (4.7 vs 4.4). The gap is mostly about Large-batch home canners and homesteaders processing pints and quarts at season's end — particularly buyers who want a lifetime-purchase tool with no gasket maintenance and verifiable pressure control across 5, 10, and 15 psi. — read the strengths below before deciding.

American homesteaders treat the 921 as a generational tool. Its patented metal-to-metal seal removes the single most common failure point on pressure canners, the rubber gasket, and the heavy cast aluminum body with triple bayonet clamps holds pressure with virtually no siphoning through long quart-jar processing. At 21.5 quarts it lands at the practical sweet spot for batch canning (19 pints or 7 quarts). All-American's lifetime warranty and 30+ year owner reports back up the heirloom-purchase framing.

Strengths
  • Patented metal-to-metal sealing system — no rubber gasket to dry out, replace, or fail in service
  • Built in Wisconsin from heavy cast aluminum with a lifetime warranty and 30+ year owner reports
  • 21.5-quart capacity processes 19 pint jars or 7 quart jars in a single load — the canning standard
Watch-outs
  • Heavy — 17.75 lb empty, well over 40 lb fully loaded with jars and water
  • Premium price puts it well above gasket-sealed canners in the same capacity class
  • Lid can be hard to remove after a long process without occasional oiling of the sealing surface

3 sources2 derived$329.95as of Jul 3

Pressure-cooker precision without losing programmable convenience is what the Fast Slow Pro sells at the high end. Dual sensors hold target pressure within a tight tolerance, and eight selectable pressure levels plus three auto-release modes give recipe-grade control no budget multi-cooker offers, in a brushed stainless build that suits the price. TechGearLab ranked it their pick for cooking performance and meat preparation; Consumer Reports tested it against multi-cooker peers across pressure, slow, rice, steam, and saute modes.

Strengths
  • Dual top-and-bottom sensors monitor temperature and pressure for tighter operating control than single-sensor multi-cookers
  • 11 pressure cook settings and 8 selectable pressure levels (1.5-12 psi) for fine-grained recipe control
  • Hands-free auto steam release with Quick, Pulse, and Natural modes — no need to manually toggle a valve
Watch-outs
  • Premium price — roughly triple the cost of a mainstream electric multi-cooker like the Cosori 6-Qt
  • Lid spills condensation when opened, a recurring complaint in long-term ownership reviews
  • 1-year warranty is short for a premium-priced appliance

How they stack up

All-American 921 Cast Aluminum Pressure Canner (21.5-Quart)

The 921 is the heirloom large-batch workhorse — the right pick when canning capacity and gasket-free reliability matter more than the lower cost of a gasket-sealed alternative. Compared to the Presto 01362 6-Quart Stainless Steel Pressure Cooker, the 921 is built for a fundamentally different job — that Presto is a 6-quart everyday stovetop cooker, the All-American is a 21.5-quart batch canner. It is also the wrong tool for general weeknight cooking compared to the Kuhn Rikon Duromatic Inox 5L Side-Handle Pressure Cooker, the Fissler Vitavit Premium 8.5 Quart Pressure Cooker, or any electric multi-cooker like the Breville Fast Slow Pro BPR700BSS — those are cookers built for everyday meals; this is a canner first.

Breville Fast Slow Pro BPR700BSS 6-Quart Multi-Cooker

Premium counterpart to the Cosori 6-Qt Electric Pressure Cooker — both are 6-quart electric multi-cookers but the Breville costs roughly three times as much. The Breville earns the premium with dual sensors, eight selectable pressure levels, hands-free auto steam release, and brushed stainless build. Versus the stovetop premium tier — the Kuhn Rikon Duromatic Inox 5L Side-Handle Pressure Cooker — the Breville trades heirloom durability for programmable convenience, and trades induction independence for plug-in countertop simplicity. For serious canning the All-American 921 Cast Aluminum Pressure Canner is the architecturally correct choice; the Breville is a cooker first.
