It is for sure cool for the retro KDE vibes but thats what it is, old buggy KDE code. Konqueror is not maintained anymore, and either they ported everything to Qt6 or their Qt is also EOL, as well as a ton of other apps.
Apart from being well tested, newer software is mostly just better. Plasma 6 is a huge cleanup and its quicker and better than ever (long time users recognize that, even though its under the hood).
