to me, the obvious answer is hybrid.  it's always better to make the solution fit the situation rather than one blanket solution.  that said, i love that i don't even have to think about fitting fully dynamic clothes.  one of my issues with fitting clothes, including using built in morphs, is that they don't really work, usually.  that is, they follow the figures morph precisely, rather than just fitting differently.  it sounds subtle, but it's the reason a lot of renders look ridiculous: the artist dialed up the figure's muscles, applied the built in morphs, and what you have is clothing that bulges oddly and has a very action figure flow.  dynamic clothes handle that better, in general.  that said, i still mostly use conforming clothes, because that's mostly what's out there in the types of clothing i like.  people mostly don't put lots of detail into dynamic clothes, even though it seems possible.

deecey- i have to say this.  a hybrid pantsuit or realistic jeans would be absolutely invaluable.  every single render i've done with pants makes my boyfriend grimace because of how unrealistically they balloon around the shin and ankle.  even after postworking away the ballooning, it doesn't pass the grimace test, because it still looks immobile.  he's taken to saying, "i just don't think poser can do pants right."   if you look closely at adzan's avatar at daz, he's got a figure sitting where the pants fold correctly. 

conversely, i don't know of a dynamic pair of jeans with as much detail as the conforming ones i have (young soul: vanilla, for one).  maybe a hybrid pair is the answer.
