2007 X5 or Escalade

[Denalio]

I've been lurking on this board for a while now. I need a new SUV or SAV. I am selling my beloved Denali. I like what I see so far in the new X5. I've narrowed my two choices down to the X5 or the Escalade. Then I have to decide between the 4.8 or the 3.0. I need to tow a couple of jetskis also. Escalade has the horsepower, size and cargo advantage and smooth ride. I love my wifes 5 series BMW. Can anyone chime in and give me some advice on both of the choices? I realize these are two different beast, apples and oranges. Any thoughts would be appreciated especially anyone who has found themselve in the same position or has owned both.

Thanks.
