Cons
Con Poor file manager
pcmanfm-qt is lightyears behind its GTK version.
Con Very limited in customization
Very few themes available, especially modern themes.
Con Ugly
Con Multiple application sources
Which leads to an inconsistent desktop.
Con Not a full desktop environment
Like LXDE or Xfce it is not a full desktop envirnment and is missing many utilities that need to be borrowed from other desktops which will bloat the desktop.
Con UHD screens hardly supported
DPI settings are not adopted. The readability, usability of this DE on UHD screens is not advisable. Fonts are not scaled at all.
Con Unthemeable for usual users
As all Qt desktop environments themeing is hard since you need to know C++ , there is a sideway using qss however its not as powerful as GTK, Enlightenment or Windows theming.
Con Depends too much on KDE
Even the programs/apps shipped with LXQt are from the KDE project. They don't have their own projects yet.
It's pretty similar to Budgie that depends on Gnome for almost everything.
Con Pcmanfm-qt needs gvfs
you can mount drives with mount, but pcmanfm uses gnomes gvfs to mount drives.
Con Missing Features = Lightweight
For the LXQT developers, lightweight is a synonym for missing features.
Con A lot of bugs
This is a very disappointing desktop environment, it's very buggy. Although there still is hope that these issues will be resolved.
Con Not quite ready for open deployment
In the current state, LXQT is a beta desktop that feels like a heavy alpha. A lot of the tools and underlying features are in a testing state, while the LXQT project itself has not had a gold (1.0.0) release as of yet.
Con Not very customizable
Con Bling Bling instead of features
Con Great DE, horrible distro
The Deepin linux distro offers its own empty package manager, and has lots of bugs. The DE and core apps are great though.
Con Buggy
Many features do not immediately work.
Con Not installable on Ubuntu/Debian
[UPDATE: Check out UbuntuDDE, a project trying to get DDE on Ubuntu and usable to normies like you]
At least, not easily, and not without potential problems. If you Want Deepin DE, use Deepin Linux, or grab Manjaro's DDE spin, or install manually on Arch Linux. Antergos, ArchLabs or similar.
Con Poor translations
Con Goes contrary to the concept of customizability
If you want non-configurability, go back to windows or mac. This is a step back for Linux.
