and

for years now, but recently I've noticed that they're not always updated. I don't just mean not updated within minutes of a new release - I mean not updated for months!

I'm now using:

and managed to catch up on several series which I thought had been dropped. Most notably Kirarin Revolution. It was 10 episodes ahead, although still quite far behind the raws <_<
