Is the Samsung Galaxy S21 Ultra better than the iPhone 12 Pro Max?

Samsung Galaxy S21 Ultra vs Apple iPhone 12 Pro Max is an interesting comparison. Both phones are undoubtedly at the height of smartphone tech, with exceptional specs, fantastic cameras and eye catching design.

But often, this one comes down to personal preference. Some people only use iOS and that will likely never change, and vice versa for Android. If you’re in camp Android, the S21 Ultra is the phone for you.
