One brilliant XDA developer named nimrodity put together the biggest database of custom Android ROMs.
The database is a gigantic Google Docs spreadsheet, which you probably won’t even understand. Heck, I barely understand what I’m looking at.
Although “custom ROMing” isn’t easy, installing a ROM from the list can help boost the performance and feel of your Android device.
Nimrodity posted a couple of videos to the custom ROM comparison XDA thread explaining the features and purpose of the comparison database.
