The searches I ran ("gillingham", "city" and "James Atkinson") didn't turn up up massively different results across google, yahoo, bing and ask jeeves, though there were some small differences. I was more intrigued, though, with some of the other features such as the Popular Q&A on ask jeeves and the Related Searches on bing which looked fun and useful.
The meta search engines were the real revelation for me - I can't understand why these aren't used more - why search one engine when you do the lot - zuula seemed the best, and most random at times - which just makes it all the more fun, of course - esp when it reminds you of your Victorian namesake's hair remedy: http://www.uniquebottles.co.uk/PotLids1.htm
A google a day might be the coolest thing I've seen here, and a good way to round things off.
