Things that stay are Studios, Time Warp, Extra Energy, Items for Girls.

You can reach higher girls without extra Studios and without extra Energy. Your favorite girl can change.

What you cannot substitute is the time warp bonus.

But if I had to choose between a 20 diamond studio and a 200 cost x8 speed up and I have 100 diamonds, I would buy the studio first.
