Why are you opposed to using a Sense rom? Sense 6 is very lean and gets out of its own way very well with great battery life, so you might be missing out on more than you think. Hawknest just released an update for Ecliptic that's inverted, so if you need a dark theme then there ya go. No one can really tell you what's best, you just need to do what Youngtusk suggested and try them all for yourself.
