The ease of setting up models; it is very intuitive which makes building new models quick & easy! Also great documentation as well!! I have been able create my own custom scoring functions using R language but so far haven't used any of their out-of box solutions (yet). It would be nice if they had more prebuilt functionality that can easily integrate into existing codebases rather than having users build from scratch every time we need something like this - maybe there are some things in progress? We use ScaleInfereince at our organization where each customer has an account manager who helps set everything up according to specifications given by them. This saves us lots of work later when problems arise because someone else made changes without consulting you about what was expected.
