It is certainly not a bad trilogy by any means, like I said, one of my favourites as a child, and I can see why people keep it in their favourite slot still now.
My current EU favourites (although I still need to get round to reading a lot of it) are:
The Thrawn Trilogy (Shock horror
)
Outbound Flight (Okay, I'm Thrawn biased)
Jedi Academy Trilogy
Republic Commando Series (The first book took me a lot of tries to get into, but afterwards it was one of the best stories I have read. Ends a little abpruptly as the series was cancelled, but I still reccomend it very highly.)
The Legacy of the Force Series (Never heard anyone else's opinion on these books, but I personally found it a very well done story)
I still need to get around to the new canon, the only stuff I know from there are the films, some of The Clone Wars, and to my shame, none of Rebels or any new comics or books. That will be a while however, I'm currently in the process of digitising my entire EU collection (and adding new stuff to it) which will take a very long time. I would love to have it all physically, but space is an issue, and a lot of the novels are old and hard to find, with the comics being even harder (although it does seem like Marvel is doing a nice job of republishing Dark Horse's stuff)
