Which coins do you think will be affected the most with the upcoming upgrade?

Closing in on the upgrade on the 14th of April, this is a simple beginner-question by many people who love the visionary concept of crypto but don't have the technical knowledge or the time to invest in researching. There are so many coins working with Eth. Which ones do you think will be affected most positively with the upgrade?

I would appreciate your opinions or a discussion about it

Thanks
