Decisions need to be based on one's particular needs. look at the components of each bike. look at the cost to replace components and keep them serviced. For instance, I prefer a $50 9 speed cassette to a $300 12 speed. I prefer cable actuated brakes because they work fine for me without extra cost or service. Other than that, the bike needs to fit you. Some styles will fit you better even when they are the same size.
