I prefer classic sharepoint
I really don't like the new theme.
I much prefer the original sharePoint theme. It is very hard to tell folders from files in the new theme. The flat colors make everything blend.
I also don't like that it becomes harder to copy a link to share. Dropbox lets you right click and copy the link. If you use your new theme, you have to click multiple times, select a link type and all kinds of stuff just to share a link.
This is why I'm still using the classic style using the "Return to classic sharepoint" but sharepoint seems to randomly forget that I want everything to be classic....

Classic forever! Too much white (wasted) space!

The modern experience is nowhere near as intuitive as classic SharePoint. It often just doesn't work. Any new capability pales in comparison to what Microsoft is removing. To many essential features have been removed i.e. no connected web parts. Stop threatening to remove the classic experience, until the modern view is fully baked, and provides all the functionality of the classic view!
