Personally im a dynamic cloth freak :D

Try as much as possible not to use conforming cloth, it simply looks to stiff in my opinion, and very often you get weird poke throughs and bad bending with a lot of poses. And the time it takes to fix those ill rather use in the cloth room, and to be honest i find it a lot faster than fixing conforming cloth. I dont think i spend more than maximum 1 min to set up a cloth simulation with everything. And if you have saved it as a smart object its pratical just pressing 3 buttons and then calculate it.

But when that is said conforming cloth is very good for solid clothing like armors etc. And you can get better details into it, that would most likely kill the cloth simulations. 

So for me it depends on what type of cloth im using, but for all fabrics it will be dynamic cloth without a doubt, looks a lot more alive and can simulated movement of the character and its always fun to see what you end up with in the end as you are never really sure.
