Alternative to dolphin

[riccardo.noc]

Hi all,
can you suggest me a good alternative to dolphin? I am using Kubuntu 13.10. Is there something similar or, I hope, better?
Thank you all in advance :)

Some KDE old-timers still use Konqueror, but I prefer Dolphin.

You might use Krusader (http://www.krusader.org/) as well, but I prefer Dolphin too.

I been enjoying Marlin. I haven't tried many others. But seems to do the job well
