You misunderstand - I'm just qualifying the experience I'm speaking from. I've used both languages, but only when time and space efficiency can't be sacrificed. I've never worked on a large program in either. Under those conditions, I know from experience that C++ is better. It allows me to abstract safely (I benefit from some compile time type-checking) with little or no run-time cost.
