The main benefit of the enameled ones is that they're lower maintenance because you don't have to worry about keeping them seasoned. The wives' tale about not cooking wine or tomato-based stuff in regular cast iron because the acid can cause metal particles to leach into the food is largely a myth, as long as your cast iron vessel is well-seasoned and cared for.
That said, enameled cast iron is not as good for searing meats because it shouldn't be used over high heat - it can stain the enamel coating and cause cracking/chipping. Regular cast iron like a Lodge skillet can go over a fully cranked burner, under the broiler, or even on your grill with no issues as long as you've got good oven mitts to protect yourself and can deal with a little smoke.
I will also add, regular cast iron should not be used on those fancypants ceramic flat-topped electric ranges - I've found out the hard way that it can cause cosmetic damage to the ceramic surface. Never buy one of those ranges if you can avoid it. The house I'm renting has one, and after several months of use I'm convinced there is not a range you can buy that is more annoying to use and keep clean than one of those things. The burners are also terrible conductors, as you might imagine.
I literally only use my cast iron to sear meat, agreed.
enameled for everything else
