What's your favorite online channel guide?

I've used http://www.titantv.com for years, I like the site and the user interface, but they tend to take a long time to get the latest channel changes. What services to others use?

www.zap2it.com works decently, I have a few custom channel lists there.

I have never found a good one that covers it all though and displays everything very nicely, etc. You would not think it would be that hard, but it must be.

I would love one that just emulated the receiver's guide.
