Help with choosing a bike

Hi,
I'm a new rider and I'm finally ready to get a new bike...I've been to 3 or 4 LBS and all of them tell me a different thing...I've been doing my research and hopefully have gotten my list down to 3 bikes. I've been looking for a bike that can handle light trails when I'm out riding with my husband as well as something that I can ride 30 or so miles a day on. I'm looking at the Giant roam 1 or 2,specalized vita or one of the kona bikes....any thoughts??
Thanks for your help!!:)

They carry my size and I've gotten on the roam 1 and like it...but since I have a knee injury I don't want a bike that is as heavy as my Boulder...
