I am unconvinced that there is much difference at all between brands — beyond personal preferences. Statistically, some may be more durable than others, but you are not gonna get much insight on that here. I can tell you that Trek road bikes are the best because I have ridden many thousands of miles on mine for the past 16 years with no problems, but that is just one man’s experience. Then next person you ask might tell you his frame broke in two the first time he hit a pothole. Neither his, nor my own, experience really tells you much about what to expect if you were to buy one.
I would go with what fits you best, and what components are best, within the budget you have to work with.
