The basic answer to your question is yes they would be the same. However you have one other setting to consider and that is ISO. In order to increase the your shutter speed time you would also need to increase the ISO. This may result in more noise int he image but will get you a higher shutter speed. I can not find the link right now but I think it was Grandpa that had a great link to illustrate the all three work in coordination to give you proper exposure, hopefully he will see this post and send it your way.
