Cons
Con Might not work well with distributions that are based on more recent packages
This is a display manager forked from GDM2 by the Linux Mint developers. So the display manager is developed alongside Linux Mint, and since Linux Mint is based on the latest Ubuntu LTS it might not work well with distributions that are based on more recent packages.
Con Depends on GTK and its dependencies
Con Unmaintained
Console TDM has never been updated since 2015. You should instead use CDM, tbsm, or any other option because such an unmaintained program could lead to potential security issues. Like CTDM, tbsm can run Wayland sessions.
Con No customization
Apart from changing the console colors there isn't much you can do.
Con Very old
The display manager looks ancient and will look ancient due to the lack of customization.
