It's great if you love food! It's great if you love wine (or beer)! It's, well, pretty great!
There will generally be a lot more food offerings form countries not represented in the World Showcase. You get small tasting portions, but keep in mind that "eating around the world" can really add up, both in money and calories! They also have a concert series, and all kinds of presentations and seminars, etc. (stuff I haven't bothered with). October is a GREAT time to go as the weather is nice and it is overall less crowded (though F&W does draw).
Some people don't like the weekend nights at Epcot because it can get a little wild, though I've never seen any really bad behavior personally. It is definitely crowded though! You can always avoid these times if you prefer.
