ICC profiles will print differently depending on environment, print head type and condition, media being used, ink being used and how the file's color settings are setup. For this reason, asking which profiles works for someone else is not going to do you much good. An actual example I have experienced is a profile I use in Denver that works very well put too much ink down during an install in Seattle.
So to answer your question, the best profile to use with your machine, in your environment, and with your material is a custom made one using a spectrophotometer and profiling software.
The second best profile to use would be one that you found through trial and error. Make a color chart and print it out using as many profiles and settings that you can. Pick the one that looks best and run with it.
