I’m gonna have to go with the one on the left, even though the black level has been lifted a bit. I am looking more at the toolbar across the top and its functionality, which looks easier to use to me.

Doesn’t matter how sleek and shiny something looks if I don’t know how to use it.

I think that the closest thing you will find to PastePal is CopyQ.

I’m a huge fan of Joplin. It runs on everything and syncs to either your or their cloud. Been using it for a few years now.
