I've had both over the years, I have had a cast head crack & fail. The pressed ones do look flimsy, but I've never had one fail. Despite the failure of the cast one in the past, I actually prefer cast over pressed, there's something reassuring about that solid lump of metal. Probably irrational considering my previous experience. Theoretically cast will be brittle, whereas pressed will be ductile & "stronger". This probably accounts for the difference in appearance, cast needs to be chunkier & massively constructed to allow for the brittle nature of the metal.
