7 Day / 14 Day Ticket

Hello,

20-24 February Tokyo Exploration
24 February : Tokyo to Kyoto
25 February : Kyoto to Osaka / Osaka to Kyoto
26 February : Kyoto to Nara / Nara to Kyoto
27 February : Kyoto to Osaka / Osaka to Kyoto
28 February - 2nd March : Kyoto Exploration
2nd March : Kyoto to Hiroshima / Hiroshima to Miyajima
4th March : Miyajima to Hiroshima /Hiroshima to Tokyo
4-6 March : Tokyo Exploration
6 March Ginza to Haneda AirPort

Do you think it makes sense to buy a 14-day ticket or a 7-day ticket? 7 Days Jr Pass + individual tickets is more economical?

Thanks for your help
