Is one just lighter or is one that much sturdier than the other. Thanx

In general, as you move up the Shimano line, the components get lighter in weight, crisper to operate and better finishes. Honestly, I find it difficult to differentiate if I move up or down one group, but I think that I can clearly feel a performance difference if I move two groups.

Doesn't one of the Shimano groups, I thought it was Tiagra, have STI shifters that resemble Campy (on the inside of the hood rather than under the brake lever)?

The alivo's do. Not sure about tiagra. They feel pretty good for cheap shifters.

actually I think it is the Sora, I just went from Tiagra to 105 and the shifting is much more consistent
you were thinking of Soraweiwentg

but the thumb button is very small and cannot be actuated from the drops. Sora is utter crap. Tiagra shifters, on the other hand, were much, much better than would be expected of a cheap group.

and they're the only STI to have brake reach adjustment.
to tell the truth left /triple version/ shifter works better with triples then my Ultegra ever did. No 9sp.
