AutoCAD vs. Inventor

[NextPerception]

The way I see it is that AutoCAD is to Inventor as Dos is to WIndows XP
AutoCAD gives you more control while it may take you longer where as Inventor looks nicer and takes less time. I wanna here from fellow AutoCAD devotees and the Inventor Buffs about why you like your software better. who knows, mabye you convert me. all I know is i have never once come up against something i can draw in autoCAD's 3D enviroment and why learn a new program if the one i am using works fine. like the old saying goes, why fix what aint broke.
