Hi, met. As far as I am concerned, the maple is as good or a better choice than oak. And the only hesitancy at all is that I, personally, like the character of oak more. And don't forget that every bowling alley in the country has maple lanes. And what do they make the best butcher blocks out of? That ought to tell you something about its durability. Just be sure that you are getting hard maple and not soft maple. There is a tremendous difference.
As far as the wine spilling incident, this has nothing to do with the wood. This is strictly a function of the finish. Any good floor finish would not allow the wine to come in contact with the wood. And any wood would absorb the wine in about the same way if it was unfinished.
So there you have the basics of a good hardwood floor, the wood and the finish. You have to have both of them and if you do, you will have beautiful floors for a long time.
