IMO, both Scalish and Marcello run last for the following reasons; from what I can see Scalish had a solid career and a good life, but he died relatively young. Marcello on the other hand, lived longer, but had a very tumultuous life, served several significant prison terms, and in the last years of his life had gotten a very bad case of dementia. He didn't even know who he was anymore.

So for those reasons, I eliminated those two names.

The other three each lived low-keyed successful lives. Lived long, made millions, served virtually no prison time, and enjoyed themselves. If you're gonna be a mob guy, I imagine thats who you'd wanna be, no?
