A homeowner chainsaw chain is fine for occasional use.

Probably. The differences matter mostly if you’re cutting wood for a living. For the occasional fallen branch or weekend firewood pile, the cheaper chain works just fine.

Pro chains use better steel — harder, stays sharp longer, less stretch. They also have more aggressive cutting angles, so they eat through wood faster. But that speed comes at a cost (literally) and they’re harder to sharpen properly.

Homeowner chains are made of softer steel, dull faster, and stretch more over time. But they cut fine when sharp, cost half as much, and are easier to maintain with a simple file.

If you’re not cutting every day, the homeowner chain is where you save money. Just keep it sharp and replace it when it’s done — don’t try to get three more cuts out of a dull chain. That’s where people get into trouble.

Unless you’re a logger, a pro chain is a waste of cash.
