Every new Pokemon generation begins with the same question: Which version should you get? Like every pair of new generation games before them, both Pokemon Sword and Shield offer different experiences for players. None are as drastic as the differences between Pokemon Black and White, but you will find different Pokemon and encounter different Gym Leaders depending on which version you play.
In the video above, Kurt Indovina details the differences between Pokemon Sword and Pokemon Shield. The main change revolves around the Gym Leaders you'll fight. Both versions have eight Gyms each, but only six are the same across both games. In addition to the aforementioned six, in Pokemon Sword you'll also fight Bea, the fighting Gym Leader, and Gordie, the rock gym leader; in Pokemon Shield, you also go up against Allister, the ghost Gym Leader, and Melony, the ice Gym Leader.
There are version-exclusive Pokemon, too--over a dozen beyond the legendaries on the two versions' covers. Farfetch'd and its new evolution, Sirfetch'd, are exclusive to Pokemon Sword, for example, as are older Pokemon, like Mawile. Meanwhile, Pokemon Shield has new Galarian Ponyta as an exclusive, as well as the much older Sableye. For the full list of exclusive Pokemon, watch the above video.
If you're on the fence about picking up one (or both!) of the new Pokemon games, don't be. They're very good. In GameSpot's Pokemon Sword / Shield review, Kallie Plagge wrote, "In collecting, battling, and exploring, Sword and Shield cut out the bloat and focus on what makes these pillars of the Pokemon games so captivating in the first place. You're not held back by overly complicated back-end systems or hoops to jump through; from the outset, you can start wandering the Galar region, seeing its new Pokemon, and trying out its new battle strategies with very little in your way. This leaves you free to enjoy what Pokemon is all about, and that makes for an incredibly strong showing for the series' proper debut on Switch."
