Zircher's right, it depends entirely on your skills and cash availability. It also depends on whether you have a mortgage, live-in lover and/or expensive car on hp.
"3D Animation" also covers a broad spectrum. DB is a 3D animation program, but so is TrueSpace and you would never use one in place of the other (unlike Pizzas and Beer Mats, which are to a certain extent interchangeable, and beer-drenched pizza can be pleasant).
Still, this question doesn't beat the "Milkshape or 3DS Max?" question from a couple of months ago.
