I think it is much more important to ask how is your bike equipped. Will it accept fenders? A rack (if you need one), protect your pant cuffs from getting greasy? Have a saddle that won't be impacted by rain/snow, Accept wide enough tires to discourage flats. Plus depending on the quality be able to be confident where you lock it, it will likely not find its way to another persons house. In my experience the style of the bike is much less important.
