My first real bike way back in 1982 was a Panasonic with Shimano 600ex. Great bike that logged tens of thousands of miles. Several years ago I found a bike with Tricolor 7 speed. It has become one of my favorite bikes. I can certainly understand why people think so highly of 600. I also have a dura ace 7700 bike. Dura ace is wonderful but it can be finicky sometimes, bottom bracket, freehub, front mech. In my opinion TC has all of positives of DA without the nit picky negatives.
