With the top set, i'd go with #4 minus the subtitle, with the 2nd set I'd go with number 1. I'm not a fan of the metal to be honest. Yes, it makes the text stand out. No, it does not feel like it's very integrated with what's going on with the background elements. Seems like layered effects for little purpose. I always prefer a cleaner look, maybe I'm biased.
