The S25 Ultra no longer offers the absolute best in mobile hardware, but its software experience, especially AI features, are the best of the bunch.

Of course, the biggest difference here relates to the size of these two phones. The Galaxy S25 Ultra is huge, measuring 162.8 x 77.6 x 8.2mm and weighing a hefty 218g. The Pixel 9 Pro is much more pocketable, measuring 152.8 x 72 x 8.5mm and weighing 199g.
