Deepin is the most polished and beautiful distro that you can get your hands on. There are lots of eye candy for those who care. Each and every feature is well thought out and implemented. You can feel the refinement in the desktop, the design and the applications Deepin team has developed.
From the performance point of view, this distro is no way a deal breaker. I installed this distro on a laptop with AMD Brazos processor with 4 GB RAM and on a desktop with AMD Phenom II and 8 GB RAM. On the Laptop the OS was sluggish. I had tried Elimentary OS on the same Laptop and that was providing a better performance than Deepin. On Desktop, the experience was very smooth. Regarding hardware support, all the hardware I had was supported including a Belkin wifi USB adaptor.
Deepin definitely got it’s own share of few issues but nothing of those are showstopper. I am using this distro for past 2 weeks on my desktop and I feel this is a distro I can keep in my computer. Deepin is a linux distro which got most of the things right, and will be a suitable substitute for any proprietary OS. You should try this distro and maybe you will love it and can even think of switching you entire family to Linux with Deepin 15.1.
