There is so much wrong with that post that I don't really know how to address it properly (What does a mythic have to do with anything? They range anywhere from significantly better to disappointingly worse. Not to mention that if you have the means to make a mythic, a relic isn't going to really detract from the process unless you're talking about years of collecting).
From what I know mathematically combined with what I've used or have:
Spharai (I probably have a bit of a bias here because I play Monk the most)/Ragnarok/Mandau/Annihilator are good. Amanomurakumo and Bravura will also be best in some situations. I can't really speak on Kikoku/Guttler/Gungnir. Excalibur is fun but underwhelming, so is Apocalypse. If you plan to be using a relic, you should generally have the appropriate merit WS, of course.
It seems counter-productive to tell someone else what they should be making, though. Make what you like, just be aware of when you should be using it and where something else might be more pertinent.
