I'd say yes. It's a lot of fun. Girl in the OP is in both versions and you meet her along the way as you defeat the gyms.
Differences between the versions are the professor(female in Scarlet, male in Violet), the uniform color, the motorcycle legendary and 16 version exclusive pokemon(half are from old gens), but you can trade for those.
Personally I'd choose based on the professor/motorcycle pokemon you like the most because they're plot relevant and your motorcycle is like a big dog and gets very cute scenes, but you do you.
