In the spirit of Ketho's list I was curious about the most popular UI compilations on WoWInterface:
- LUI: 646,151
- SpartanUI: 316,199
- Roth UI: 251,670
- Caith UI: 191,852
- ElvUI (Tukui-based): 179,672
(Tukui, including user edits, is pretty popular, but not available for download here on WoWI.)
These numbers suggest to me that, while compilations are much less popular than certain individual AddOns, 100% replacement of Blizzard's UI graphics is a popular compilation attribute. (No sh*t
)
