Should I play Hitman 2?

Hey there

I've played Hitman 2016, and then I bought Hitman 2 (2018) but never played it. Now, I know the Hitman 2 missions are included inside World of Assassination so, here is my question:

Should I play the Hitman 2 I already own, or is it better to wait and buy World of Assassination and play through Hitman 2 and 3 missions in there?

Do we get to see the story in World of Assassination, or only the gameplay part of the missions?

Did it make playing Hitman 2 obsolete?

Thanks
