Quick verdict
The decision between these two H-frame hydraulic shop presses comes down to how the tonnage is labeled and how much worktable adjustability you need. Both are new H-frame presses with adjustable height, and both include a safety valve that activates beyond 6 tons. If you want a title that states the tonnage directly, the 12/20 Ton H-Frame Shop Press is the straightforward choice. If you want a press that spells out its adjustable worktable in the product details, the 6/12/20 Ton H-Frame Shop Press is the one to weigh.

Where each product wins
The 12/20 Ton stands out for tonnage clarity
The 12/20 Ton press puts its dual-tonnage label right in the title, so it is easy to identify when scanning H-frame presses. The H-frame design uses carbon steel and is described as stable, and the overall package stays focused on capacity. If the exact capacity phrase matters to you, this is the press that states it.
The 6/12/20 Ton stands out for adjustability and coverage
This press answers with a 5-year warranty and an adjustable worktable layout that includes two repositionable press plates. The worktable can be repositioned by height, which helps when you plan to adjust the working height between tasks. That makes it the press to consider when adjustability and long-term coverage are the priority.
Product notes
12/20 Ton Hydraulic Shop Press,H-Frame Press,Adjustable Height,Movable Plates

Pick the 12/20 Ton Hydraulic Shop Press when you want the 12-ton capacity and 20-ton pressure capacity written into the title itself. The built-in safety valve is described as preventing overpressure above 6 tons, and the H-frame carbon steel construction is described as stable and robust. The $129.99 listed price is $4.60 higher than the 6/12/20 Ton model, so the trade-off is cost. For that difference you get a headline that says 12/20 Ton directly, along with the same H-frame layout. If the exact dual-tonnage wording is what makes a shop press feel like the right match, the price difference is the price of that clarity.
6/12/20 Ton Hydraulic Shop Press,H-Frame Press,Adjustable Height,Movable Plates

Choose the 6/12/20 Ton Hydraulic Shop Press when you want an explicit worktable height range of 1.6 to 27.8 inches. The limitation is that its 6/12/20 Ton title is broader than the 12/20 Ton title's tight dual-tonnage message; if you prefer the simpler 12/20 Ton label, the other press states it straight. The adjustability detail is the reason this model makes sense when you need to reset the working height between jobs.
Final choice by use case
For pressing wheel bearings, straightening metal, and stamping work where the tonnage phrase is the deciding factor, the 12/20 Ton Hydraulic Shop Press is the straightforward pick. For setups where you want the worktable adjustability, the 6/12/20 Ton Hydraulic Shop Press is the one to choose. Both are H-frame presses, so the final call is between title-level tonnage clarity and extra adjustability detail.
