The "Liv" is a woman's bike, in case you didn't realize.

Those bikes you list are all decent, low end bikes.

The important thing is to find a bike that fits you and you enjoy riding. I would suggest that you visit your bike shop and see if they will let you try out any of the bikes. Make clear that you have a budget limit, and remember that you'll need to budget for things like helmets, water bottles, cages and clothing.
