Howard Hughes hits the nail on the head. Direct entry commands on jets are fairly rare unless you want to head to some foreign location. Even then you won't get DEC unless you already have jet command. And you won't get that at home unless you start RHS. So if jets are your ambition, every year in turboprops is time lost toward the ultimate goal.
But which is the more satisfying job? Probably turbo-prop command. But can you live on satisfaction alone, or does ambition drive you? Your call.
