There are two Ellucian SIS products: Banner, and Colleague. Colleague is touted as the smaller, cheaper option for smaller schools. Banner is the full-fledged SIS with all the bells and whistles. They have pretty decent documentation, "action line" support, and a forums community. Join your local "Banner Users Group" as well for more resources. Ethos is going to be great for integration but at this time there's not enough stuff using it, and not enough customizability there. Anything you want - Ellucian has, but you need to make sure you set it up right the first time. Go for the training, consultants, all that. They know how to work their product the best.

If you're transitioning from one SIS to another, there's no such thing as an easy implementation - it will be a nightmare to transfer all of your stuff. Because it is it's own "beast", it will require extensive training. They're pushing everyone to SaaS which would be fine if you're already moving from one place to another, but if you've been on prem or hosted, it is not a good idea to move to SaaS. Also, their support sucks. You'll find great agents in individual departments but as a whole, they are so silo'd and as soon as a problem isn't specific to that one domain, well, you're going to have issues because they'll throw your ticket back and forth to different departments and point the finger at everyone else.
