There is no black and white ranking here as there are a lot of different kind of models which float around these days claiming to be prop shops. As one of the guys above mentioned, I prefer the first loss funding kind of firms where I put in my capital, get 20-25x leverage for a certain split and my loss is limited to the capital I have put in. Have traded overs 12 years in different prop firms offering this and have been fairly successful thus far
It is also important to have a risk management guys in a prop, that will adjust the setup for your strategy and understand what you are doing.
