Minus Mjolnir, I've tried the rest and still prefer Slate[1] but it hasn't been updated since Feb 2013. Actually I had never heard of Mjolnir before now. I like Slate's ability to define a config file that is just a little more powerful than the competition, plus it's easy to sync across machines. I haven't updated to Yosemite, but Slate works wonderfully on Mavericks.
