The main answer to your question lies mainly in your lifestyle.
I believe Am. Cherry is a fine wood, one of my favorites.
It would not be too soft of a material for my lifestyle or my tastes.
Are you metropolitan or a rustic? Will your floor be clean and clear or do you like some character?
Do you live in a museum or do you like to tussle with the kids and the dog?
In short ... are you anal
or adventurous
?
Wood floors will indeed wear and scratch and move and do all kinds of stuff that will either infuriate or intrigue most. The most important thing to know is do you like the species, do you love how it looks, makes your home feel, complete your tastes, etc.? Will you like walking, playing, living, making memories, on it? Do you plan to enjoy your floor and how it makes you feel OR are you going to freak out everytime the doorbell rings and get all paranoid about what type of shoes your would be guest will be wearing.
Bottom Line: BUY THE FLOOR YOU LIKE? One you feel is beautiful. Get a decent finish. Then commence enjoying your new look in your home.
Did I come off as too much of a romantic?? Oh well ... hope if I couldn't answer your question I atleast gave you something to think about.
