The real question is whether the material matters for your project, because the cheaper spring and the stainless version are built around very different priorities. Both are new and open-ended, so the choice is mostly about what you're building and what you want to spend.
Quick Verdict
If you want to keep the purchase price down, the Various Size compression spring at $3.69 is the clear pick. If you need a stainless steel build, the higher-priced spring at $82.25 is the one to choose. Material is the tie-breaker between these two compression springs.

Where Each Spring Wins
The Various Size spring wins on up-front cost. It is simply the less expensive of the two, and that is the strongest argument for choosing it when you just need a compression spring. The stainless spring wins when material is a requirement, not just a preference. It gives you a stainless steel coil at a price that reflects that material choice, and it suits everything from tractors to model making. The right pick depends on whether you'd rather spend less now or match the material to the project requirements.
Product Notes
#### Compression Spring Various Size
The main reason to choose this spring is its position at the low end of the price spread. For that price, you get a compression spring with a spring steel build, plus a 2mm-to-42mm diameter range. That makes it a sensible first option for a basic compression job where stainless isn't required. The trade-off is the material: this is spring steel, not a stainless build, so it doesn't give you the stainless material that the higher-priced option offers. It is new. The low price also makes it easier to keep a spare on hand without a large outlay. If the project doesn't call for stainless, this is the lower-cost way to get the coil you need.
#### The Stainless Steel Pressure Spring
Choose this spring when 304 stainless steel is part of your requirement. It suits projects like tractors, agriculture, industry, metal construction, vintage cars, model making, and more. That range of use cases makes it easy to see why someone would pick the stainless option. The limitation is the price: it sits at the high end of the price spread, so you'll pay considerably more than the other compression spring. The stainless material is the feature you're paying for, and it is the reason to spend more. If you don't need stainless, that extra cost is hard to justify. But if you do need it, this is the spring that gives it to you. It is new.
Final Choice by Use Case
If your project doesn't demand stainless, the lower-priced Various Size compression spring is the sensible default. If you need a stainless build and the broader use-case flexibility, the stainless steel pressure spring is the one to order.
