Which are the primary differences between Pokemon Sword and Shield

[Chaostic]

Hello! I have Pokemon Shield but I would like to know which are the differences. I know that in each version there are some exclusive Pokemons like Tyranitar. But, any other difference?

Ther's a Sword Doggo in one and Shield Doggo in another

Some encounters are different (some in the grass or overworld are different, you can check serebii)
Some max raids are different (some max raids encounters are different from their counterparts, but they can be hosted for the other version, luckily. Check serebii)
Some Gyms are different: Fighting(SW)/Ghost(SH) for Stow-on-Side, and Rock(SW)/Ice(SH) for Circhester
Some NPCs are different: Gym trainers, Gym Leaders, Sordward and Shielbert (they both appear in the story, but who you battle against changes)
Some clothes are obtained differently (ultimately you can get all the clothes, but because gym leaders are different, this shifts around what you'll receive from completing the challenge, and what you have to buy)

I think this covers it?
