I prefer
DebuffFilter Since it leaves less visual spam on my screen. The colored bars, text, etc I find are much harder to digest than the icons I am used to looking at on the mob anyhow.
The screenshot doesn't show it but for debuffs you place on the target you have the option of the standard "picture radial timer" that debuffs do by default.
This mod is out of date, however (though it still works and I have had no issues). Perhaps another fine question is can Demon work in a mode similar to this? A maintained and updated mod that duplicates this display method would be awesome.
