KO vs KISS III

I've been practicing both the KO preferred and KISS III system. The sims seem to give almost equal results, however I haven't read any posts here of anyone who has successfully used the KISS system? I seem to think that the KISS basic strategy variations are more accurate than KO since KISS uses different indicies for the departures (ie more than A,B,C groups in KO). Has anyone here use KISS, or should I stick with the KO which has proven casino results. Thanks.
