[Request] Image editing software for Linux

Hello guys. I am on Debian. Can anyone suggest some good alternative to Photoshop except Gimp. Gimp is not as featureful as Adobe Photoshop. I will appreciate your help.
My system:
Running Debian 9, 8GB RAM, i5 8250u.

Better as Gimp only if you emullate windows and fave a virtual machine, where you can install Photoshop. https://www.winehq.org/
