Pros
Pro Useful for low-end devices
As Linux moves into low-end territory with the likes of Raspberry PI, CDE's level of consumption seems extremely small. When it was first developed, 128MB or RAM was a lot.
Pro Stays out of your way
Has the drawer concept and the middle button on the mouse has a use again.
Pro Mature
CDE was developed more than 20 years ago to work as a unified DE for all the various forms of commercial, proprietary Unix operating systems that dominated the market back then: AIX, TRU64, HP-UX, Solaris, IRIX etc...
Nowadays it's released as an open source Desktop Environment for Linux. It comes as a free tested, widely deployed and enterprise-level product even if it's recently re-release as FOSS for Linux.
Pro It's minimal and gorgeous
Pro It's maintained by a dedicated bunch of folks with an eye for detail
Pro Modern design
Pro Built from scratch and integrates into current technolgies
Budgie is built from scratch to integrate with the Gnome stack, this way hopefully having more stability by utilizing technologies that have a lot of community work already behind them.
Pro Very lightweight
Runs well on low-end hardware and gaming PC’s alike.
Pro Many large distros support it out of the box
Ubuntu, Fedora, Arch, and Budgie's own Solus all support Budgie.
Pro No big memory leaks
It can be run for weeks with no noticeable increase in memory usage. That is a vast improvement over gnome-shell.
Pro Can emulate Gnome 2 desktop look
The Budgie desktop can emulate the classic Gnome 2 look.
Cons
Con Outdated UI
The graphical interface is very outdated and ugly. It's mostly for lower-end machines and for people who want to give their Linux machine a true UNIX feel.
Con Not a desktop environment
It's just a replacement for the GNOME-shell and you still need a GNOME-desktop installed at the same time.
Con Sometimes buggy
Budgie can sometimes be buggy.
Con Less lightweight than you would expect
Budgie has a nice and simple style, but the memory usage is quite high after booting. Thankfully, the lead developer is working to remedy this.
Con Does not properly support multi monitor
Having two monitors works, but it's not perfect.
Con Has not switched to Qt as promised
Very dependable on Gnome
Con Very hard to install
Installing in distros that are not Ubuntu-based can be hard.
Con Lacks some basic features
Many things you'd take for granted aren't available in Budgie, like an option for showing windows from all workspaces when alt-tabbing.
Con Issues with proprietary drivers and Mutter
Mutter causes issues with screen tearing and microstuttering in most applications especially with NVidia GPUs.
Con Still in development
Budgie is still young and in active development, so it may not be as stable as many other desktop environments.
Con Just another GNOME-shell alternative
You still have to install and use GNOME software.
