ThreaDom: is 'easy' or 'Optimization' results more accurate?

I need to split a protein by domains for use with I-TASSER.
In THREADOM the resulting file produces several predicted domains: for instance, ‘easy’ produces 5 domains, however, in the ‘Optimization’ there are 2.
For the greatest accuracy, would I split the protein using the Predicted 'easy' type domain results, or is the 'Optimization' result information better to use?
