I also like how dropbox.com is using https (secure http), and Ghostery shows no sign of web beacons there (whereas imageshack has a couple). All in all, no one needs both... and the best choice is clear (imo).
I've posted this at Ghostery, and it may deserve its own thread, but please take a gander at
this and tell me what you think. (For the benefit of all, _u cookies are placed by Google Analytics, one of the "bugs" I've got Ghostery set to block. ("Blocking all bugs.")
(And while I'm revisiting the subject, I'll mention that unless I've missed something, a major advantage that ImageShackUploader offers over Dropbox is an immediate set of links on my desktop when I upload an image, whereas as far as I can tell, I've got to visit dropbox.com to link to images uploaded there.)
