Are Rogue/Unity/Syndicate worth playing?

I started with Ezio collection and just finished Black Flag. I wanted to play them all in order of release, but after AC 3 i am sceptical about the Rogue/Unity/Syndicate trilogy. The Parkour in Boston/NYC in AC3 sucked and after i checked the locations of these 3 games i just expect it to be the same. On the other hand, Odyssay, Origins and Valhalla seem much better to play, so is it worth playing the mentioned trilogy or it's skippable? Also, any opinions on the Russia/China/India spin-offs? Haven't seen much ppl mention them at all, but the titles sound interesting
