I pretty much use them interchangeably. I keep a few of each in 3/0, and whatever I grab out of that compartment will do what I need it to do. If I'm fishing water with a lot of snot in it, I might look for an offset round-bend specifically to minimize the keel that the hook shank creates, in the hopes that I'd drag back fewer boogers, but that's about it.
About the only way I fish with them hooks is unweighted worms or the like.
