When I posted my UI the other day, as well as when I posted about ArcHUD, I got a lot of Drathal's HUD (DHUD) fans telling me I should use that instead. I had tried DHUD before, but it never really grabbed me. However, I figured if so many nice WoW Insider readers liked it, perhaps I should give it another shot. MetaHUD seems to be DHUD's successor, so I downloaded that, and have been playing with it for the last day or so.
The verdict? I love it! You guys were right; MHUD is really, really nice. I'm not sure I'm going to throw away Arc just yet, but MHUD is making me very happy indeed. I think my favorite part is the casting bar, which I liked so much I put up a shoddy video on YouTube of it (please excuse my YouTube noobiness; it looks better on screen, I swear).
