Yup. Its a matter of fitting your cooking style. Agreed.
They have their uses, but I disagree with Jake above. These are most commonly used for braises and in that use neither the cast iron nor the enamel are giving you actual performance benefits.
If you like them, sure, they' cook well and are pretty enough to serve from.
On the other hand, I find them somewhat fussier to use, clean, and store than comparable heavy stainless cookware. I've used mine less and less over the years and my stainless more and more.
It's not about being wrong or right but more how they fit your cooking preferences really.
