Roger/Murray is something very, very fresh for a Grand Slam finale, and it will be a great match, I'm sure. Hopefully Roger squashes him, though.
The quality of Goran/Rafter doesn't even come close to the others mentioned. Fed/Rafa and Djoko/Rafa where both 5+ hours of the best quality tennis i've ever seen, with a bucketload of incredible rallies and winners. In both cases this was the two best players in the world (and 3 of the best ever) all playing at their peak and absolutely pummelling each other.
Fed/Roddick is a great shout though, would be in my top 5.
It wasn't the best match in terms of pure, technical tennis quality (hence why I said "greatest", not "best"), but it was something amazing, something big and grandioze, especially with Goran's background with 3 lost finals (Sampras x2 and Andre), the fact that he was an etternal underdog beloved by Wimbledon crowds and people knew what Wimbledon meant to him, the fact that he was dog's shit at the time, and yet somehow managed to play a perfect tournament, and especially after he defeated Henman in epic war in semis, God it was an awesome watch. Not to mention, it was arguably the hottest crowd ever for a tennis match, I mean they were going BALLISTIC for both guys, because Pat was insanely popular too.
The tennis quality was top notch too, Pat's net game was something beautiful, Goran was one handy motherfucker too, and the drama was unbelievable. I will use a wrestling term here, and say it was a perfect, cinematic storytelling, and it was fucking special for us Croats.
