Answer:
Yes, language and culture would be different, daily life not necessarily so.
Explanation:
If the Spanish had overtaken the Jamestown colony, and had expanded from there to other parts of North America, they would have sent settlers from Spain to promote their language and religion: Spanish and Christian Catholicism, respectively.
The U.S. would still be a Western Nation, but more similar to Latin America than it is right now.
Daily life would not necessarily be that different. The country would have likely industrialized, and then, become a service-based economy, meaning that most people would have more or less the same lifestyle and jobs that they have today.
