Looking for new lens for Nikon D3100?

Does lens brand matter when it comes to buying a zoom/telephoto lens? I'm looking at getting either a 55-200mm or a 70-300mm, and I have found that tamron brand is slightly cheaper for the lens. Now i know the whole, cheaper price cheaper quality thing, but as a general public, does anyone have opinions/advice?

The Nikkor 55-300 mm may be a good choice

Brand does not matter. But every model of lens have different build, and thus affecting the looks of the pictures.

I will recommend sites like cameralabs.com for reviews. Find a lens that best fit you and your budget.
