I like a more uniform color for flooring so of these the one on the right but you need to see more than one piece of sample board to really get the look you want. As for the style of the house a few pics of your ideas would be helpful. When I google this style it is all over the map for flooring and decor. Maybe post some pics in an idea book for us to at least see what is in your mind.

Since both are White Oak it seems unlikely that one would have less variation than the other. Both are nice and frankly I'd have a hard time choosing if this was for my own home. Compare the samples to your other selections and any existing furnishings you might be using. When you think you've decided it's a good idea to buy a whole box and look at it to confirm your selection.
