Contact and speed is a great combo and equates to a good increase in batting avg and OBP. You can pretty much take batting eye (whatever the figure may be) and add that to the avg for the OBP, and get pretty close.
Having said that, I would rather have a lineup full of guys with batting eye over 90 than contact over 90. Getting on base via a walk is a guarantee, making contact is not, depending on what the defense does.
