I had an EG classic for 4 years and just sold it to buy my 2007 SERK. The EG is a very smooth and comfortable bike but it is HEAVY. I took it on a few long trips (Sturgis '05 and Nova Scotia '06) and on the highway it is lovely (altough I will say that going 70 mph on an interstate makes the stereo very hard to hear!). My biggest problem was the weight of the bike in traffic or in crowded places. It is not an easy machine to turn in a smallish radius. In fact I tipped it over on the highway bars a few times. On the other hand, the SERK feels alot more manageable for me. Sure, it doesn't have the batwing and the radio, but the weight distribution feels very comfortable to me.
It is clearly a personal preference. They are both nice, but keep in mind that the SEEG will not be as manageable in slower traffic or crowded conditions. Anyway, that was my experience. I am very happy with the SERK.
