Both build on their 2017 predecessors, with stunning curved 5.8in and 6.2in AMOLED screens respectively, minimal bezels and great cameras.
Why upgrade? The S9+'s 12MP sensor boasts a dual aperture that allows it to switch between f/1.5 and f/2.4 apertures, making the best of any dark situations for a decent snap.
And both sport all-new Exynos 9810 processors that make an already lightning-quick phone even faster. No wonder they both killed it in our reviews.
These are the best deals on both right now. We'll update this page as new deals go live, so bookmark it and check back regularly.
