Regarding Noodler's Ink: Most of his popular inks are fairly consistent. Noodler's Ink Black being by far the most popular. For black inks I prefer Heart of Darkness. It is a deeper, richer black, though it isn't as well-behaved on bad paper.
Noodler's Navy is also very good. (I have many bottles from this brand.)
But if you want a safe-in-any-pen, just works, generally great ink, I'd have to recommend Pilot Blue-Black in the 70ml bottle. The bottle has built-in ink well, so it ensures you get a good fill all the way through the life of the bottle. The ink is middle of the road for wetness (Pilot Iroshizuku inks are wet, this is in the middle, not dry like Robert Oster inks, for example).
