I like ICDF - I guess that's my case for it. EDF is definitely more powerful and easier to achieve, although I don't know very much about electrics. Actually, I know little to nothing. My best bet as far as EDF is concerned is to see what the active people are using and copy their set ups. I simply don't know enough to design my own.

ICDF, on the other hand, I know quite a bit about and I really enjoy the noise, smell, goo, mess and fuss. That's what keeps me interested. It's also very cheap these days and that can be a positive. YMMV
