To put it in another perspective... There are a crap-ton of Walmarts out there, but you do not see them lined up one after another on the same street.
Yeah, they go by Walmart, Sam's Club, Marketside, etc... (All Walmart stores being fed from the same warehouse)
Good thing you didn't say like Berkshire or some other conglomerate that owns every other chain you see driving down the street. Because then you'd be REALLY wrong, just not wrong.
I suggest you get to making your own set of sites with unique content to compete. Look at it this way: Each site can/will attract a little different viewer just by it's innately different slant and search metrics.
