Buying advice

Which should you buy?

The Galaxy S25 Ultra is the clear pick on raw spec strength, leading by 10.7 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

Pick the Galaxy S25 Ultra if you photograph or shoot video regularly and want the better imaging pipeline of the two. The biggest gaps in its favor are main camera, wired charging, ram, among others.

The iPhone 15 Pro Max similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.

Both ship with comparable refresh rate, 5g support, water resistance, so those specs don't separate the two — focus on the differences below.

Bottom line: the Galaxy S25 Ultra is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
