(...instead of continuing the old topic, where I started it, but it went too far from the original point, I state the question here.)

How does the Shimano 600 Ultegra sti shifter compare to newer Tiagra one? Would the newer, but lower end shifters function better than older one.

I ask because my bike has all Shimano 600 compnents (probably early 90s, dark grey), yet the shifters are from Tiagra. I saw locally a good deal on almost new looking Shimano 600 shifters (the same group as my derailleurs, with this three colored stripe under the name). I am tempted to get it as it looks so much better, but I have no idea, how it would function in comparison with my current set. Apart from one being 8 and the other 9-speed, what are the other differences?
