Example characteristics can be: affordability, ease of pushing and steering, ease of folding, ability to grow with your family, aesthetics, weight, and availability of high-end features like a bassinet attachment or large storage basket.
If you care about affordability, ease of folding, and ease of pushing and steering, the Baby Jogger City Mini GT2 stroller is a great option. If you care about the ability of the stroller to growth with your family, ease of pushing and steering, and high-end features, the Uppababy Vista V2 stroller is another popular option. If you have twins, the Bugaboo Donkey 5 stroller could be a great fit with its side-by-side double configuration.
