I have been a Plasma user since version 5.18.
I started using Solus this week, it's a notebook:
Acer Aspire E 15 (E5-571-33ZU)
i3-4005u 1.7 GHz
Intel HD Graphics 4400
As a notebook, I chose to try GNOME, while maintaining another distribution with Plasma on the PC.
I'm very surprised by the performance of GNOME on Solus, I've never seen GNOME so light and fast.
If I install Solus on PC+NVIDIA, I'll choose Budgie, I only hear compliments.
I'm not a developer, but I'll be promoting the name Solus to the Linux community in my country.
Thank you, the project is very wonderful.
