Cons

Con Not a display manager
Qingy is not a display manager - it is a getty replacement.
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.
