Con Not very advanced
Pantheon files (like Elementary OS itself) does not offer many advanced features since it's mostly aimed at beginners.
Was missing basic network connect features when Loki launched.
Con KDE dependencies
If you don't use KDE, you'll be forced to install quite a large amount of KDE libraries.
Con Interface can be overwhelming
Con New releases are infrequent
It can be seen in https://quickgit.kde.org/?p=krusader.git that maintenance work is done in a continous fashion, but no new releases are provided.
Even though it is perhaps the more feature-rich file manager.
