Hey there, thanks for contributing! Unfortunately, I flagged this one since it's better to have one general idea per pro, so editing and commenting will be easier and more clear for others. Also all of these points have already been covered in other pros. Hope you don't mind and thanks again!
Have you checked Deepin 15.8? Starting from Deepin 15.7 it has started to become lighter than before.
First, I had checked the website. It claimed that it is now lighter than Ubuntu.
Then, I checked it by myself. I installed both Ubuntu and Deepin.
From my experience, I can now tell that it is lighter than Ubuntu.

I'm marking this as duplicate and leaving the original as it is.
Hey! Unless you got different sources, all the spyware references I can find about deepin point to this post in which the issue was discussed and the conclusion was that it is intrusive but it is just run-of-the mill traffic analytics, but not spyware per-se. Have there been other incidents? Do you have more concrete or up to date information about this?
