The simplest answer is to follow the subscription you already pay for. If your household has Netflix, FM27 Mobile costs you nothing extra and is the quicker way in. If you already have Apple Arcade or an Apple One plan, Touch is waiting for you.
If you’re paying for neither, think about how you play. The Netflix edition is described as the faster, more streamlined take on the series. For Touch, Apple’s pitch centers on control: the new scouting and preparation tools, plus more ways to shape a match while it’s being played.
There’s also the device question. Apple says its own Arcade Originals run on iPhone, iPad, Mac, Apple TV and Apple Vision Pro, while titles it labels App Store Greats work on iPhone, iPad and Vision Pro only. Apple’s announcement doesn’t say which group Football Manager 27 Touch belongs to, so check the game’s App Store page if you hope to continue a save on a Mac or your TV. The Netflix edition, by contrast, is phone and tablet only for now, because Netflix’s cloud gaming service doesn’t carry the full PC or console game.
