I will admit that I have a favorite brand of ink, now. Yes, the Waterman's ink is alright. It works, and the green and the turquoise are really pretty.
But I must say that Noodler's ink has become, far and away, my absolute favorite. Not only is the ink of very good quality (and much of it is water resistant or waterproof, with a few freeze resistant varieties), but the company has a sense of history and sense of humor that is rarely found today.
They have inks like Q-E'ternity (a blue-black that happens to nod toward the endless rounds of quantitative easing), Nikita Khrushchev red, Tiannanmen (also red, but a little darker), a collection of colors inspired by WWII (Burma Brown, Mandalay Maroon, Operation Overlord Orange, etc)...
...and the one I just ordered: Bernanke Blue. A quick drying ink named after the Fed Chairman Ben Bernanke, who was the main face of the frenzied printing of money that was Quantitative Easing. There's also a quick-drying Bernanke Black.
Neither color is permanent, only water-resistant and smear resistant.
