I preferred mirage, which I put on the same strength level as semi-duals; most of the LSEs that I've met seemed to have had their own opinions and ambitions while most of the SEIs behaved somewhat like acolytes going with the flow and spouting the opinions of others and avoiding controversial issues. Now, I've butted heads with far more LSEs than SEIs who tend to be far less offensive. However, I prefer to know where I stand with people and SEIs can be rather opaque.
