Enterprise Library Unity vs Other IoC Containers

I've been introduced to several IoC-containers during these past few months, and so far I can't really see a big difference from StructureMap, Windsor or Unity for that matter.

Often I have heard groans from more senior developers I know when I mention that I use Unity.

Which one do you prefer, and why do you hate some other IoC-containers?

Answer 1

I have used Unity quite a lot but I like the look of Autofac - it has some nice features that seem to be missing from the others.

Answer 2

It's not what you use, it's how you use it. I like Unity.

Answer 3

Spring is an awfully popular flavor of this. I've used it as part of Apache CXF, and I've used it for my own projects.
