What if Earth had no axial tilt?

After seeing a post on r/unpopularopinion, I started wondering what our planet would be like if it had no axial tilt. I'm pretty sure that it would have a more stable and colder climate, especially in the polar regions, but I'm looking for other people's opinions.<br><br>Let's suppose that Earth's orbit remains the same as it does today, with the exception of the axial tilt. What do you think the result would be?
