i've got micorshift on multiple bikes. absolutely love it. WAY better than sora or tiagra, probably more in line with 105 or ultegra in terms of function and it's lighter than all of them perhaps even dura ace too if your counting grams. the shifting from the drops is way better than sora but not totally ideal. The cost of microshift makes it well worth it. you can buy 3 sets of micorshift brifters for the cost of one set of ultegra. thats a no brainer to me.
