I always liked IE for one reason -- it was the easiest browser to use if you wanted to make a bookmark! Kind of like buying a car because you like the glovebox . . . )
Remember back when this pretty much started, how there was such competition between Internet Explorer and Netscape? I tried to keep both equally up to date for 2-3 years not really knowing much about it. That got old. But I agree, IE's bookmark system has always suited me very well.
