Which editor you should get really depends on how dedicated you are to editing. If you're REALLY into it, getting something like Sony Vegas, Final Cut Pro or the like is a good idea. If you only do editing as a pastime once every now and then and don't devote a lot of your time to it, I wouldn't bother buying a top-notch program, because they tend to be expensive.
Personally, I loved fighting Groundshaker (aka the big frikkin' boss at the end of the second visit to the Pride Lands). Mainly I enjoyed it because when you knock him down via reaction commands, I like to whip out Simba's limit and watch the HP bar fall...plus, he's freaking HUGE.
Well, in KH1 I had a very rough time beating Anti-Sora (And yet a friend of mine beat him in only 3 tries when he first got into KH...I was so jealous D:), plus not being able to skip cutscenes was such a load of turd. That's one thing I love about the second game.
In KH2, I was very frustrated to see Atlantica turned into a musical world (although Sora's not a shabby singer), and I'm also one of the very many that was frustrated with the Demyx battle until I learned that Stitch is a GODSEND for that fight.
